get specific data filed from returned object in java

Let’s say this is somewhat like your Emp class.

public class Emp {
    private String  name;
    private int     number;
    private int     salary;

    public Emp( String name, int number, int salary ) {
        this.name = name;
        this.number = number;
        this.salary = salary;
    }

    /* some methods */
}

Make another method called (for example) getSalary like this

    public int getSalary( ) {
        return salary;
    }

Then use it as follows

Emp e = new Emp("aBc", 12415, 02125);
System.out.println(e.getSalary()); // will print 2125 because that's the salary
