这题太恶心了，直接放代码，变量rate写的有点懵逼，估计也就我自己看得懂

import java.util.Scanner;

public class LoanTest{
	public static void main(String[] args){
			Scanner sc = new Scanner(System.in);
			double capital = sc.nextDouble();
			int year = sc.nextInt();

			System.out.println("贷款额："+String.format("%.0f",capital));
			
			System.out.println("贷款年限："+year);
			System.out.println("利率    月还款额    总还款额");
			
			// double rate = 0.05;	//利率
			
			double sum = 0;		//总还款额

			double month = 0; 	//月还款额
			for (double rate = 0.05; rate <= 0.08125; ){
				month = (capital * (rate / 12) * Math.pow(1 + rate / 12,year * 12)) /
						 (Math.pow(1 + rate / 12, year * 12) - 1); 
				
				sum = month * 12 * year;
				rate = rate * 100;
				System.out.println(String.format("%.3f",rate) + "%	"+String.format("%.2f",month) +"	"+String.format("%.2f",sum));
				rate = rate / 100;
				rate = rate + 0.00125;

				 
			}
			
			
			
		}
}
