1.Make the class as final
2.Make the data members as private
3.write the public getter methods
Ex:

public static void main(String[] args) {
ImmutableTest it=new ImmutableTest(10,"Count");
System.out.println(it.getString());
System.out.println(it.getValue());
}
}
final class ImmutableTest{
private int i;
private String str;
public ImmutableTest(int i,String str){
this.i=i;
this.str=str;
}
public int getValue(){
return i;
}
public String getString(){
return str;
}
