错误“小时无法解析为变量”，我做错了什么？-解网

问：

    Scanner kb = new Scanner(System.in);
    System.out.println("Please enter a military time: ");
    int time = kb.nextInt();
    int minutes = (time%100);
    if (time < 1){
        System.out.println("Illegal time, please give another one.");
    }else if (time%100>59){
        System.out.println("Illegal time, please give another one.");
    }else if (time>2400){
        System.out.println("Illegal time, please give another one.");
    }else{
        if (time<100){
            final int hours = 12;
        }else if (time<1300){
            final int hours = (time/100);
        }else{
            final int hours = ((time/100)-12); }
        if (minutes<10)
            System.out.println("Standard time is: "+hours+":0"+minutes);
        else if (minutes>=10)
            System.out.println("Standard time is: "+hours+":"+minutes);

这是一个将军事时间转换为标准时间的程序。我不断收到错误“小时无法解析为变量”，但不明白我的代码出了什么问题。任何洞察力的帮助都会有所帮助。

Java 变量

final int hours;  // Not initialized yet.
if (time<100){
   hours = 12;
}else if (time<1300){
   hours = (time/100);
}else{
   hours = ((time/100)-12); }
// Now it's still in scope here:
if (minutes<10)
    System.out.println("Standard time is: "+hours+":0"+minutes);
else if (minutes>=10)
    System.out.println("Standard time is: "+hours+":"+minutes);

请注意，编译器足够聪明，可以确定变量在每种情况下都只初始化一次，因此它不会抱怨变量可能未初始化，或者变量在初始化后可能已更改。finalhours

Error "hours cannot be resolved to a variable", what am I doing wrong?
