1、while循环
题目1:输出1~100
package struct; public class WhileDemo01 { public static void main(String[] args) { //输出1~100 int i = 0; while (i<100){ i++; System.out.println(i); } } }
题目2: 计算1+2+3+...+100?
package struct; public class WhileDemo01 { public static void main(String[] args) { //计算1+2+...+100? int i = 0; int sum = 0; while (i<=100){ sum = sum+i; i++; } System.out.println(sum); } }
