获取两个数并比较大小（java 学习）

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

public class CompareNum {
	public static void main(String[] args) {
		//InputStreamReader isr = new InputStreamReader(System.in);接受从控制台输入的字节
		//BufferedReader br = new BufferedReader(isr);
		BufferedReader br =new BufferedReader(new InputStreamReader(System.in));
		try {
			System.out.println("请输入第一个数");
			//从缓存中读取一行的内容
			String num1 = br.readLine();
			
			System.out.println("请输入第二个数");
			String num2 = br.readLine();
			
			//float fnum1 = Float.parseFloat(num1);
			//float fnum2 = Float.parseFloat(num2);
			
			int fnum1 = Integer.parseInt(num1);
			int fnum2 = Integer.parseInt(num2);
			
			//int fnum2 = Integer.parseInt(num2,16 );
			
								
			
			if(fnum1>fnum2) {
				System.out.println(fnum1+"大于"+fnum2);
			}
			if(fnum1<fnum2) {
				System.out.println(fnum1+"小于"+fnum2);
			}
			if(fnum1==fnum2) {
				System.out.println(fnum1+"等于"+fnum2);
			}
			} catch (IOException e) {
				System.out.println("无法判断");
				
		}
