Java While Loop

The while loop or while statement continually executes a block of statements while a particular condition is true. The while syntax can be written as:

while (expression) {

The while loop evaluates expression, which must return a boolean value. If the while loop expression returns true, then the statements with in the while block will be executed. The while loop continuesly executes the statements within the block, until the expression returns false.

Here is a simple while loop example, which executes until i value became 10:

package com.java2novice.loops;

public class SimpleWhileEx {

	public static void main(String a[]){
		int i=0;
		while(i < 10){
			//this block will executed until
			//i value became 10
			System.out.print(i+" ");

ServletOuptputStream Vs PrintWriter
ServletOutputStream: ServletResponse.getOutputStream() returns a ServletOutputStream suitable for writing binary data in the response. The servlet container does not encode the binary data, it sends the raw data as it is.

PrintWriter: ServletResponse.getWriter() returns PrintWriter object which sends character text to the client. The PrintWriter uses the character encoding returned by getCharacterEncoding(). If the response's character encoding has not been specified then it does default character encoding.
