在 Java 中呼叫另一個方法中的變數

public class CallAVariable {
    static int y = 4; //declared inside class scope.
    public static void main(String[] args) {
        String val = "Hello"; //declared inside the scope of main method hence available in main only.

        System.out.println("In Main where static variable y is: "+y);
        callInNormal(val);
      
    }
    public static void callInNormal (String val){
        System.out.println("Value of static variable y in a static method is : "+y +" and String passed is: "+val);
      
    }
}

In Main where static variable y is: 4
Value of static variable y in a static method is : 4 and String passed is: Hello

public class CallAVariable {
    int x = 2; 
    static int y = 6;
  
    public static void main(String[] args) {
        //since the method is non static it needs to be called on the instance of class.
        //and so does the variable x.  
        CallAVariable  i = new CallAVariable();
        System.out.println("In Main where static variable y is: "+y+ " and x is: "+i.x);
        i.callInNormal(i.x);      
      
    }
    public void callInNormal (int x){
      
        CallAVariable i = new CallAVariable();
        System.out.println("Non static variable x is : " +x+" and static variable y is: "+y);
      
    }
}

In Main where static variable y is: 6 and x is: 2
Non static variable x is : 2 and static variable y is: 6
