Show warning when user generate only getter and in the code there is also value assigned to this value.

Example:
public class TestClass {    
    public int x;   
}

public class TestClass2 extends TestClass{
    public void method() {
        x  = 3;
        System.out.println(x);
    }
}

Encapsulate field x - select only creating getter and change access modifier to private
-> the x will not be accessible in line x=3;
