java中沒有goto，但是goto是保留字。例如int goto;是不合法的。
但是java中有標簽，僅作用在多重循環的continue和break中。
continue和break只能作用於本層循環，但是有了標簽可以直接跳出多重循環。
代碼舉例：
public class Main {
public static void main(String[] args) {
first: // 標簽與循環直接不可以加語句
for (int i = 0; i < 3; ++i) {
System.out.println("\nfirst: " + (i + 1) + " times start");
second:
for (int j = 0; j < 2; ++j) {
System.out.println("\tsecond: " + (j + 1) + " times start");
if (i == 1 && j == 1) {
System.out.println("\t----break----");
break;
}
for (int k = 0; k < 2; ++k) {
System.out.println("\t\tthird: " + (k + 1) + " times start");
if (i == 1 && j == 0 && k == 0) {
System.out.println("\t\t----continue----");
continue;
}
if (i == 2 && j == 0) {
System.out.println("\t\t----continue second----");
continue second;
}
if (i == 2 && j == 1 && k == 1) {
System.out.println("\t\t----break first----");
break first;
}
System.out.println("\t\tthird: " + (k + 1) + " times end");
}
System.out.println("\tsecond: " + (j + 1) + " times end");
}
System.out.println("first: " + (i + 1) + " times end");
}
}
}
輸出：
first: 1 times start second: 1 times start third: 1 times start third: 1 times end third: 2 times start third: 2 times end second: 1 times end second: 2 times start third: 1 times start third: 1 times end third: 2 times start third: 2 times end second: 2 times end first: 1 times end first: 2 times start second: 1 times start third: 1 times start ----continue---- third: 2 times start third: 2 times end second: 1 times end second: 2 times start ----break---- first: 2 times end first: 3 times start second: 1 times start third: 1 times start ----continue second---- second: 2 times start third: 1 times start third: 1 times end third: 2 times start ----break first----
