Write a program to calculate Semester Performance Index (SPI).

import java.util.*;

class CalculateSPI {

String grade[] = new String[5];

int credit[] = new int[5];

int totalcredit;

int totalpoint;

double SPI;

Scanner sc = new Scanner(System.in);

CalculateSPI() {

for(int i = 0; i < 5; i++) {

System.out.print("Enter Subject " + (i+1) + " Grade : ");

grade[i] = sc.nextLine();

System.out.print("Enter Subject " + (i+1) + " Credit : ");

credit[i] = sc.nextInt();

System.out.println();

sc.nextLine();

totalcredit += credit[i];

if(grade[i] .equals ("AA") || grade[i] .equals ("aa")) {

totalpoint += credit[i]*10;

}

else if(grade[i] .equals ("AB") || grade[i] .equals ("ab")) {

totalpoint += credit[i]*9;

}

else if(grade[i] .equals ("BB") || grade[i] .equals ("bb")) {

totalpoint += credit[i]*8;

}

else if(grade[i] .equals ("BC") || grade[i] .equals ("bc")) {

totalpoint += credit[i]*7;

}

else if(grade[i] .equals ("CC") || grade[i] .equals ("cc")) {

totalpoint += credit[i]*6;

}

else if(grade[i] .equals ("CD") || grade[i] .equals ("cd")) {

totalpoint += credit[i]*5;

}

else if(grade[i] .equals ("DD") || grade[i] .equals ("dd")) {

totalpoint += credit[i]*4;

}

else {

totalpoint += credit[i]*0;

}

}

calculateSPI();

}

void calculateSPI() {

SPI = (double) totalpoint / totalcredit;

System.out.printf("SPI : %.2f", SPI);

}

}

class SPICalculationDemo {

public static void main(String args[]) {

CalculateSPI student = new CalculateSPI();

}

}

Output :
