All other operations are done first; and then Decrement is done at the end. These operators are used for testing, complementing or shifting bits to the right or left. A list of seven Bitwise operators as follows 1.
Core Java: An Integrated Approach
Bitwise OR 4. Truth Table: It gives the relations between input bits to output bits. It acts upon three variables so it is called ternary Operators. Output: Membership or. Dot Operators: This operator represents the membership. Dot operator can use as follows To refer to class and interfaces of a packages.
Class Ex: java. BufferedReader; To refer to variable of a class. Instanceof Operators: This operator is useful to know whether an object belongs to a class or an object.
New Operators: This operator is useful to create an object to a class or an object. Using control statements it is possible to create computers and difficult programs with complex or critical logics. Control statements are divided into 3 parts, they are 1. Branching Statements 2. Looping Iterative statements 3. Jump statements Branching Statements: Branching conditional statements can be divided into two parts they are Un Conditional Conditional Un Conditional: goto: The keywords goto are reserved but not used.
In the early days of Java, it is a UnConditional Statement; Java does not allow the goto control statement because a mass of tangled jumps and conditional branches that makes a program virtually impossible to understand. Conditional: if else: This conditional statements executes a task one or more statements depending upon whether a conditional is true or not. If none of the statements are selected in the switch statement then default case will be executed by default.
Switch Statement is most suitable to Menu Driven programs. Looping Iterative statements: A loop iterative can execute several times but a statement can execute in one time there are four types of looping statements.
When the loop first starts, the initialization portion of the loop is executed.
Generally, this is an expression that sets the value of the loop control variable, which acts as a counter that controls the loop. Initialization: It is important to understand that the initialization expression is only executed once. Next, condition is evaluated. It usually tests the loop control variable against a target value.
If this expression is true, then body will executed. If it is false, the loop terminates. The loop then iterates, first evaluating the conditional expression, then executing the body of the loop, and then executing the iteration expression with each pass.
This process repeats until the controlling expression is false.
For loop is used to execute for a fixed no. A loop that is executed for ever is called infinite looping statement. Nested Loops Java allows loops to be nested. That is, one loop may be inside another.
Using foreach statement each element of an array arr will executes.
Java supports three jump statements: break, continue, and return. These statements transfer control to another part of your program. Break: In Java, the break statement has three uses. First, as you have seen, it terminates a statement sequence in a switch statement.
Second, it can be used to exit a loop. Third, it can be used as a civilized form of goto. The last two uses are explained here. Using break to exit a loop Ex.
When this form of break executes, control is transferred out of the named block of code. The labeled block of code must enclose the break statement, but it does not need to be the immediately enclosing block. This means that you can use a labeled break statement to exit from a set of nested blocks.
But you cannot use break to transfer control to a block of code that does not enclose the break statement. This is after second block. Continue: It is useful to force an early iteration of a loop. That is, you might want to continue running the loop, but stop processing the remainder of the code in its body for this particular iteration.
Here is an example program that uses continue to cause two numbers to be printed on each line: Ex.
Core Java ByR.nageswara Rao
Here is an example program that uses continue to print a triangular multiplication table for 0 through 9. The return statement is used to explicitly return from a method. That is, This return statement immediately terminates the method in which it is executed and come back to the calling method. This return statement can be return some resulting value to the calling method. The following example illustrates this point: Ex.
Return statement in main method will terminate the application. What is difference between System.

API Application Programming Interface documentation is a file that contains discretion of all the features of softwares, a product, or a Technology. API Document is created by using the java doc compiler. A stream is an abstraction that either produces or consumes information.
Ex: Play a video or audio file as it downloads from the Internet. There are two types of streams 1.
InputStreams: They are reading or receive the data. OutputStreams: They are writing or send the data.
All streams are represented as classes in java. The Predefined Streams: All Java programs automatically import the java.
This package defines a class called System, which encapsulates several aspects of the run-time environment. For example, using some of its methods, you can obtain the current time and the settings of various properties associated with the system. System also contains three predefined stream variables, in, out, and errs. These fields are declared as public and static within System.
This means that they can be used by any other part of your program and without reference to a specific System object. By default, this is the console.
These are byte streams, even though they typically are used to read and write characters from and to the console.
Here we can wrap these within character-based streams. The object of InputStreamReader to the keyboard object. The preferred method of reading console input for Java 2 is to use a character-oriented stream, which makes your program easier to internationalize and maintain. Reading Characters: To read a character from a BufferedReader, use read. The version of read that we will be using is int read throws IOException Each time that read is called, it reads a character from the input stream and returns it as an integer value.
It returns 1 when the end of the stream is encountered. As you can see, it can throw an IOException. The following program demonstrates read by reading characters from the console until the user types a q: Ex.
This output may look a little different from what you expected, because System. As you can guess, this does not make read particularly valuable for interactive, console input. Reading String: To read a string from the keyboard, use the version of readLine that is a member of the BufferedReader class.
The following program demonstrates BufferedReader and the readLine method; the program reads and displays lines of text until you enter the word stop: Ex. Enter 'stop' to quit. It creates an array of String objects and then reads in lines of text, storing each line in the array. It will read up to lines or until you enter stop. It uses a BufferedReader to read from the console. Home Core Java: An Integrated Approach, New: Includes All Versions upto Java 8.

BufferedWriter: A BufferedWriter is a Writer that adds a flush method that can be used to ensure that data buffers are physically written to the actual output stream.

StringBuilder Class. On reading the book, readers are able to write simple programs on their own, as this is the first requirement to become a Java Programmer. Thread Priorities. This is not a small thing to keep aside. Syntax: type var-name[ ][ ]; Here, type declares the base type for the array determines what type of data the array will hold. Sometimes you will want to pass information into a program when you run it.
