我有以下代码.

public static void main(String[] args) {
    System.out.println(returnString());
}
private static String returnString(){
    try {
        System.out.println("Executing try");
        return "Return try value";
    } catch (Exception e){
        System.out.println("Executing Catch");
        return "Return catch value";
    } finally {
        System.out.println("Executing finally");
        return "Return finally value";
    }
}

这个输出是

Executing try
Executing finally
Return finally value

如果我改变我的finally块而不返回任何类似的东西

public static void main(String[] args) {
    System.out.println(returnString());
}
private static String returnString(){
    try {
        System.out.println("Executing try");
        return "Return try value";
    } catch (Exception e){
        System.out.println("Executing Catch");
        return "Return catch …
