Program to Calculate GPA and CGPA in java

How to calculate GPA and CGPA in java?

import java.util.*;

public class CGPA_3rd_Semster

 public static void main(String[] args) 

 {

 Scanner obj = new Scanner(System.in);

 double ds,eng,discrete,network,hrm;

    System.out.print("\t\t***___Created By Jhangir Mughal___***");

 System.out.print("\n\nEnter Data Structure Gpa:> ");

 ds=obj.nextFloat();

    System.out.print("Enter Discrete Structure Gpa:> ");

 discrete=obj.nextFloat();

    System.out.print("Enter Network Gpa:> ");

 network=obj.nextFloat();;

 System.out.print("Enter HRm Gpa:> ");

 hrm=obj.nextFloat();

 System.out.print("Enter Critical Reading and Academic Writing Gpa:> ");

 eng=obj.nextFloat();

 double gpads,gpaeng,gpadis,gpanet,gpahr;

 gpads=ds*4;

 gpaeng=eng*3;

 gpadis=discrete*3;

 gpanet=network*3;

 gpahr=hrm*3;

 double totalGpa,tcredhr=16;

 double CGPA_2ndsem,T3rd_CGPA;

 CGPA_2ndsem=(firstSem+secSem)/(credhr1st+credhr2nd);

 System.out.print("\nYour CGPA in 2nd semester:> "+CGPA_2ndsem);
