java - 是否可以退出 if 语句并返回到内部 for 循环？

Question

是否有命令退出内部 for 循环内的 if 语句并让它仅通过该内部 for 循环？

例如:

for (int i = 0; i < blah.length; i++) {
    blh = scan.nextDouble();            
    blah[i] = blh;

    if(scores[i] < MIN || scores[i] > MAX_SCORE) {
        errFlag = true;
        System.out.println("ERROR: Enter numbers in the range of " +
            MIN + "-" + MAX_SCORE + "!");
        System.out.print("ERROR: Enter all " + numStudents + " scores again: ");
        errFlag = false;
    }                       
}

Answer 1

你可以使用标签 block

FOUND: {
    for(Type mt: TypeList)
       if(condtion(mt))
            break FOUND;
    // not found code here
}

根据 Java Language Specification 14.7

A labeled statement is executed by executing the immediately contained Statement. If the statement is labeled by an Identifier and the contained Statement completes abruptly because of a break with the same Identifier, then the labeled statement completes normally. In all other cases of abrupt completion of the Statement, the labeled statement completes abruptly for the same reason
