Java 循环中的 break、continue 和 label
java programming java8java technologies object oriented programming
以下示例展示了 for 语句前的标签 'first'、'second'，并使用 break/continue 控件跳转到该标签。请参阅下面的示例。
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 导致循环跳过 print 语句 if i = 1;
second 是第二个最外层 for 循环的标签，continue second 导致循环中断循环。
