简单的题目, 就是练习if...else if...else...语句的题目, 水题:

import java.io.BufferedReader;
import java.io.InputStreamReader;

public class Main {

    public static void main(String[] args) throws Exception{
        BufferedReader br = new BufferedReader(new InputStreamReader(System.in));
        String[] str = br.readLine().split(" ");
        int A = Integer.parseInt(str[0]);
        int B = Integer.parseInt(str[1]);
        if (B==0) {
            System.out.print(A+"/"+B+"=Error");
        } else if(B > 0) {
            System.out.print(String.format(A + "/" + B + "=%.2f", (float)A/(float)B));
        } else {
            System.out.print(String.format(A + "/" + "(" + B + ")" + "=%.2f", (float)A/(float)B));
        }
    }

}
