实在不懂你的程序想干啥
import java.util.Scanner;public class Test {    public static void main(String[] arg) {        Scanner input = new Scanner(System.in);
        int leftmoney;
        int salary;
        int give;
        int credit;
        System.out.println("Enter leftMoney:");
        leftmoney = input.nextInt();
        System.out.println("Enter salary:");
        salary = input.nextInt();
        System.out.println("Enter give:");
        give = input.nextInt();
        credit = leftmoney + salary - give;
        while (credit < 0) {            System.out.println("Credit limit exceeded");
        }    }
}
