如何调用方法并打印其结果？

public class Test {

    public static int main (String args[]){

        System.out.println(total);

    }

    public int numbers (int a, int b){

        int total;
        total = a + b;
        return = total;
    }
}

Answer 1

请改为尝试：

public class Test {

    public static void main (String args[]){

        System.out.println(numbers(1, 2));

    }

    public static int numbers(int a, int b){

        int total;
        total = a + b;
        return total;
    }
}

变量的范围限定在定义它们的方法或类中，因此总数为＆＃39;变量只能在＆＃39;数字中访问。方法

公共课测试{

public static void main (String args[]){

    System.out.println(numbers(anumber,bnumber));  

}

public static int numbers (int a, int b){

    int total;
    total = a + b;
    return total;
}
