whileloop.java

非常好的java事例以及带源码事例的java2教程

public class WhileLoop 
{
  public static void main(String[] args) 
  {
    int limit = 20;                     // Sum from 1 to this value
    int sum = 0;                        // Accumulate sum in this variable
    int i = 1;                          // Loop counter

    // Loop from 1 to the value of limit, adding 1 each cycle
    while(i <= limit)
      sum += i++;                      // Add the current value of i to sum
    System.out.println("sum = " + sum);
  }
}
