        System.out.println("Name :"   name);
        System.out.println("Department :" dep);
        System.out.println("Age :" age);
        System.out.println("Blood-Group :" bdg);
        System.out.println("Hobbies :" hob);
    }

public class display {
    public static void main(String[] args) {
        msg d=new msg();
        d.data();
        d.showdata();
        System.out.println("Welcome to java development !!!");
    }
}

How do I call these variables – > name, dep, age, bdg, hob – > inside the method showdata() and print that details, is there any option to call another variable of another method in a different method but in the same class

defaultjava.java:32: error: cannot find symbol
     System.out.println("Name:" name);
     ^
  symbol:   variable name
  location: class msg

CodePudding user response：

Posting OPs solution since they're unable to do it themselves.

The solution is to make the variables in question members of the class by defining them outside of any methods:
