if return跳出执行函数

使用if return代替if else，return 会自动跳出该执行方法。

import java.util.Scanner;
public class PartB5
{
    public static void main(String[] args)
    {
        Scanner keyboard = new Scanner(System.in);
        int number = keyboard.nextInt();
        if(number == 1)
        {
            System.out.println("猜对了");
            return;
        }
        System.out.println("猜错了");
    }
}

上述代码相当于

import java.util.Scanner;
public class PartB5
{
    public static void main(String[] args)
    {
        Scanner keyboard = new Scanner(System.in);
        int number = keyboard.nextInt();
        if(number == 1)
        {
            System.out.println("猜对了");
        }
        else
        {
        	System.out.println("猜错了");
		}
        
    }
}
