循环结构

package struct;public class WhileDemo01 {public static void main(String[] args) {//输出1-100int i = 0;while (i<100){i++;System.out.println(i);}}
}

package struct;public class WhileDemo02 {public static void main(String[] args) {//死循环while (true){//等待客户端链接//定时检查//........}}
}

package struct;public class WhileDemo03 {public static void main(String[] args) {//计算1+2+3+。。。+100=？//高斯的故事int i = 0;int sum = 0;while (i<=100){sum = sum+i;i++;}System.out.println(sum);}
