打印百分比的程序中的UnknownFormatConversionException

Question

我必须编写一个程序,我在其中输入棒球统计数据,并且它出现了持续击打平均值,然后重新说出了玩家的名字,然后把它放在了一个哨兵循环上.我目前的代码如下.在我把它变成一个循环之前,我试图让它与一个一起工作.当我跑去测试时,我明白了UnknownFormatConversionException.这是什么意思？我该如何修复我的代码？

import java.util.Scanner;
public class bata
{
    public static void main(String[] args) throws Exception
    {
    double ba,sp,tb;
    int tri,dou,sin,hr,ab,hits;
    String name;
    Scanner sc = new Scanner(System.in);
    System.out.print("Enter Singles");
    sin = sc.nextInt();
    System.out.print("Enter Doubles");
    dou = sc.nextInt();
    System.out.print("Enter Triples");
    tri = sc.nextInt();
    System.out.print("Enter Homeruns");
    hr = sc.nextInt();
    System.out.print("Enter At bats");
    ab = sc.nextInt();
    System.out.print("Enter Player name");
    name = sc.nextLine();
    System.in.read();
    tb= (sin + (dou*2) + (tri *3) +(hr *4));
    hits = sin+dou+tri+hr;
    sp= tb/ab;
    ba= hits/ab;
    System.out.println(""+name);
    System.out.printf("Slugging % is %.3f\n", sp);
    System.out.printf("Batting avg os %.3f\n", ba);
    }
}

Answer 1

逃生%标志,使用双%%:

System.out.printf("Slugging %% is %.3f\n", sp);
