java如何在遍历每个元素时从值中减去数组元素？

Question

我需要制定一个计划，找出哪些贷款可以发放。我还有500英镑的余额要开始，还有一系列贷款申请，都是先到先得的。我遇到的问题是没有更新我的储蓄

任何帮助都将不胜感激

public class Exercise2 {
    
    public static void main(String[] args) {
        
        int savings = 500;
        int[] loanAmount = {60, 20, 100, 80, 40, 300, 200, 100};
        int balance;
        
        for (int i = 0; i < loanAmount.length; i++) {

            balance = savings - loanAmount[i];
        
            System.out.println("Cash in the pot: " + balance + "\n" + "Loan amount requested: " + loanAmount[i] + " - " + " Loan amount granted!");
            System.out.println("Cash remaining in the pot: " + balance);
            

            if(loanAmount[i] > balance)
            {
             System.out.println("Cash in the pot: " + balance + "\n" + "Loan amount requested: " + loanAmount[i] + "\n" + "The exact loan request amount cannot be processed in full (insufficent funds available)." + "\n" + "However, we will give you what we can... " + balance);
            
            }
            
            if(balance == 0)
            {
            System.out.println("The following loan requests could not be facilitated" + "\n" + loanAmount[i] + "\n" + loanAmount[i]);
                
            }
        }
    }        
}

你在找这个吗

    package arraysAndStrings;

public class Exercise2 {

    public static void main(String[] args) {

        int savings = 500;
        int[] loanAmount = { 60, 20, 100, 80, 40, 300, 200, 100 };
        // int balance = savings;

        for (int i = 0; i < loanAmount.length; i++) {
            if ((savings - loanAmount[i]) >= 0) {
                System.out.println("Cash in the pot: " + savings + "\n"
                        + "Loan amount requested: " + loanAmount[i] + " - "
                        + " Loan amount granted!");
                savings -= loanAmount[i];
                System.out.println("Cash remaining in the pot: " + savings);
                System.out.println();
            } else if (savings > 0) {
                System.out
                        .println("Cash in the pot: "
                                + savings
                                + "\n"
                                + "Loan amount requested: "
                                + loanAmount[i]
                                + "\n"
                                + "The exact loan request amount cannot be processed in full (insufficent funds available)."
                                + "\n"
                                + "However, we will give you what we can... "
                                + savings);
                System.out.println();
            } else {
                System.out.println("No cash left!");
                break;
            }
        }
    }
