DoWhile循环
package com.guo.struct;public class DoWhlieDemo01 {public static void main(String[] args) {int i = 0;int sum = 0;do {sum = sum + i;i++;} while (i<=100);System.out.println(sum);}
}While与DoWhile的区别
package com.guo.struct;public class DoWhlieDemo02 {public static void main(String[] args) {int i = 0;while (i<0){ // 不进入循环System.out.println(i);i++;}System.out.println("========================");do {System.out.println(i);i++;}while (i<0); //至少再循环里走了一次}
}//输出结果为：
/*========================0*/
