while loop
# simple while loop python.
input output
a=1 1
while a<=10: 4
print(a) 7
a=a+3 10
# here a=a+3 can be written as 'a+=3'while loop
While(condition is true) {

// Code
}While Loop
A while loop statement in Java programming language repeatedly executes a target statement as long as a given condition is true.
Syntax :
while(Boolean_expression) {
// Statements
}
Here, statement(s) may be a single statement or a block of statements. The condition may be any expression, and true is any non zero value.
When executing, if the boolean_expression result is true, then the actions inside the loop will be executed. This will continue as long as the expression result is true.
When the condition becomes false, program control passes to the line immediately following the loop.Example of While Loop
public class Test {
public static void main(String args[]) {
int x = 10;
while( x < 20 ) {
System.out.print("value of x : " + x );
x++;
System.out.print("n");
}
}
