Java 方法来显示记录。

嘿，伙计们，我只是想帮你们完成这件事

代码段：

我需要显示我请求的记录，并将对象存储到数组中

---

这就是我被困的地方。我需要在循环中执行此操作5次，最后显示数组中的所有记录，如果有意义的话？

制作一个

ArrayList

并将所有变量添加到该列表中

ArrayList arrlist = new ArrayList();
arrlist.add(prime);
arrlist.add(LoanType);
arrlist.add(amountOfLoan);
arrlist.add(customerFirstName );
arrlist.add(customerLastName);
arrlist.add(t);

并显示

ArrayList

System.out.println(arrlist);

循环示例

int[] nums = new int[5];
String[] names = new String[5];

Scanner input = new Scanner(System.in);

for (int i = 0; i < 5; i++){
    System.out.println("Enter a number: ");
    int number = input.nextInt();

    // insert into array
    nums[i] = number;

    System.out.println("Enter a name: ");
    String name = input.nextLne();

    // insert into array
    names[i] = name;

}

int[]nums=newint[5]；
字符串[]名称=新字符串[5]；
扫描仪输入=新扫描仪（System.in）；
对于（int i=0；i<5；i++）{
System.out.println（“输入一个数字：”）；
int number=input.nextInt（）；
//插入到数组中
nums[i]=数量；
System.out.println（“输入名称：”）；
字符串名称=input.nextLne（）；
//插入到数组中
名称[i]=名称；
}

任何你想循环5次的东西，你都可以放入循环中。无论要存储什么值，也可以在循环中存储。

尝试以下方法：

import java.util.Scanner;


public class CreateLoans {
    public static void main(String[] args) {
        Scanner sc = new Scanner(System.in);
        Loan[] loans = new Loan[5];

        for(int i=0;i<5;i++) {
            loans[i] = new Loan();
            System.out.println("Please Enter the current prime interest rate");
            float prime = sc.nextInt();
            prime = (float)(prime/100f);
            loans[i].setPrime(prime);


            //ask for Personal or Business
            System.out.println("are you after a business or personal loan? Type business or personal");
            String loanType = sc.next();
            loans[i].setLoanType(loanType);

            //enter the Loan amount
            System.out.println("Enter the amount of loan");
            float amountOfLoan = sc.nextFloat();
            loans[i].setAmountOfLoan(amountOfLoan);

            //enter Customer Names  
            System.out.println("Enter First Name");
            String customerFirstName = sc.next();
            loans[i].setCustomerFirstName(customerFirstName);

            System.out.println("Enter Last Name");
            String customerLastName = sc.next();
            loans[i].setCustomerLastName(customerLastName);
        }

        //Display details 

        for(int i=0;i<5;i++) {
            System.out.println(loans[i]);
        }
    }
}

    private float prime;
    private float amountOfLoan = 0;
    private String customerFirstName;

    }
    public float getAmountOfLoan() {
        return amountOfLoan;
    }
    public void setAmountOfLoan(float amountOfLoan) {
        this.amountOfLoan = amountOfLoan;
    }
    public String getCustomerFirstName() {
        return customerFirstName;
    }
    public void setCustomerFirstName(String customerFirstName) {
        this.customerFirstName = customerFirstName;

    }
    public void setCustomerLastName(String customerLastName) {

    }
    public String getLoanType() {
        return LoanType;
    }
    public void setLoanType(String loanType) {
        LoanType = loanType;
    }

    @Override
