[JAVA] Float, Double형 소수점 자리수 정하기

import java.io.*;

public class Main{
    public static void main(String[] args) {
        BufferedReader br=new BufferedReader(new InputStreamReader(System.in));
        BufferedWriter bw=new BufferedWriter(new OutputStreamWriter(System.out));
        try {
            float f=Float.parseFloat(br.readLine());
            String s=String.format("%.6f",f); // 소수점 6자리로 변환
            bw.write(s+"\n");
            bw.flush();
            bw.close();
            br.close();
        } catch(Exception e) {
