Program:

import java.io.*;
import java.util.Scanner;

public class CreditScore
{
public static void main(String[]args)throws IOException
{

// declare and initialize variables
int creditScore;

double loanAmount,interestRate=0.0,interestAmount; // Here we are initializing interestRate as 0.0

final double I_a = 5.56,I_b = 6.38,I_c = 7.12,I_d = 9.34,I_e = 12.45,I_f = 0;
String instructions = "This program calculates annual interest\n"+"based on a credit score.\n\n";
String output;

Scanner input = new Scanner(System.in);// for receiving input from keyboard


// get input from user
System.out.println(instructions );

System.out.println("Enter the loan amount: $");
loanAmount = input.nextDouble();

System.out.println("Enter the credit score: ");

creditScore = input.nextInt(); // Here in nextInt I mst be capital

System.out.println();// print blank line

//process data

if(creditScore>=720&&creditScore<=850)
interestRate = I_a;
  
else if(creditScore>=690&&creditScore<=719)
interestRate = I_b;
  
else if(creditScore>=660&&creditScore<=689)
interestRate = I_c;
  
else if(creditScore>=625&&creditScore<=689)
interestRate = I_d;
  
else if(creditScore>=590&&creditScore<=624)
interestRate = I_e;
  
else if(creditScore<590)
interestRate = I_f;
  
interestAmount = loanAmount*interestRate;

// output
output = "The loan amount is $" +loanAmount + "\n"
+ "The credit score is" + creditScore + "\n"
+ "The interest rate is" + interestRate + "\n"
+ "The interest is $" + interestAmount + "\n"
+ "End of program\n\n";

// display output
System.out.println(output);

}//end main

}//end class
