While
What is a while loop?
- While loop is a pre-test loop which means the condition will be first checked then the statement will execute.
- The while loop repeats the statement till the condition is true.
- When the condition is false then execution comes out from the loop.
Key Points:
- In the while loop, based on the condition block statement is executed.
- it is also known as an entry control loop.
Syntax:
while (condition){
// code to be executed
increment/decrement statement; // i++
}
Example:
package quipohouse;
class WhileLoop {
public static void main(String args[]) {
// initialization expression
int i = 1;
// test expression
while (i < 4) {
System.out.println("Quipo House");
i++; // update expression
}
}
}
Output:
Quipo House
Quipo House
Quipo House
