The numerical for loop : For Loop « Statement Control « Java Tutorial

for (initialization_expression ; loop_condition ; increment_expression) {
  // statements
public class MainClass {
  public static void main(String[] args) {
    int limit = 20; // Sum from 1 to this value
    int sum = 0;    // Accumulate sum in this variable

    for (int i = 1; i <= limit; i++) {
      sum = sum + i;
    System.out.println("sum = " + sum);
sum = 210
