Java Do-While Loop

A do-while loop is similar to a while loop, except that a do-while loop is guaranteed to execute at least one time. The difference between do-while and while loop is that do-while evaluates its condition at the bottom of the loop instead of the top. Therefore, the statements within the do block are always executed at least once. Here is the syntax to write do-while loop:

do {
} while (expression);

The do-while statement evaluates expression, which must return a boolean value. If the expression is true, the flow of control goes back to the do, and the statements within the loop executes again. This process repeats until the expression returns false.

Here is a simple do-while example:

package com.java2novice.loops;

public class SimpleDoWhileEx {

	public static void main(String a[]){
		int i = 0;
		do {
			System.out.print(i+" ");
		} while(i<10);

Stream and types of Streams
A Stream is an abstraction that either produces or consumes information. There are two types of Streams and they are:

Byte Streams: Provide a convenient means for handling input and output of bytes. Byte Streams classes are defined by using two abstract classes, namely InputStream and OutputStream.

Character Streams: Provide a convenient means for handling input & output of characters. Character Streams classes are defined by using two abstract classes, namely Reader and Writer.
