Java 带标签的 for 循环
java programming java8java technologies object oriented programming
以下程序使用了带标签的 for 循环。
示例
public class Tester {
public static void main(String args[]) {
first:
for (int i = 0; i < 3; i++) {
for (int j = 0; j< 3; j++){
if(i == 1){
continue first;
}
System.out.print(" [i = " + i + ", j = " + j + "] ");
}
}
System.out.println();
second:
for (int i = 0; i < 3; i++) {
for (int j = 0; j< 3; j++){
if(i == 1){
break second;
}
System.out.print(" [i = " + i + ", j = " + j + "] ");
}
}
}
}
first 是第一个最外层 for 循环的标签，continue first 会导致循环跳过 print 语句(如果 i = 1);
second 是第二个最外层 for 循环的标签，continue second 会导致循环中断。
