There is also a do-while loop in the Java programming language. Instead of evaluating the expression at the beginning like the while loop does the do-while loop evaluates its expression at the end of the loop. Due to this the loop executes at least once during the program execution.
package org.kodejava.basic;
public class DoWhileDemo {
public static void main(String[] args) {
int i = 0;
// The do-while statement executes at least once because
// the expression is checked at the end of the loop
// process.
do {
// This block will be executed while `i` is smaller or
// equals to 10.
System.out.println(i);
i++;
} while (i <= 10);
}
}
The program prints the following result:
0
1
2
3
4
5
6
7
8
9
10
