JAVA try...catch...finally中的执行顺序和return语句

public static int get() {

    try {
        System.out.println("try");
return 1;
//throw new Exception();
    } catch (Exception e) {
        System.out.println("catch");
return 2;
    } finally {
        System.out.println("finally");
return 3;
    }
}

结果：

try

finally

3

public static int get() {
try {
        System.out.println("try");
//return 1;
 throw new Exception();
    } catch (Exception e) {
        System.out.println("catch");
return 2;
    } finally {
        System.out.println("finally");
return 3;
    }
}

结果：

try

catch

finally

3

public static int get() {
try {
        System.out.println("try");
//return 1;
 throw new Exception();
    } catch (Exception e) {
        System.out.println("catch");
return 2;
    } finally {
        System.out.println("finally");
//return 3;
    }
}

结果：

try

catch

finally

2

结论：finally块中的return会覆盖掉try或catch块中的return

    try {
        System.out.println("try");
return 1;
//throw new Exception();
    } catch (Exception e) {
        System.out.println("catch");
return 2;
    } finally {
        System.out.println("finally");
return 3;
    }
}

结果：

try

finally

public static int get() {
try {
        System.out.println("try");
//return 1;
 throw new Exception();
    } catch (Exception e) {
        System.out.println("catch");
return 2;
    } finally {
        System.out.println("finally");
return 3;
    }
}

结果：

try

public static int get() {
