【java入门】使用选择法确定输入最大值

package com.demo;
import java.util.Scanner;

public class Test4 {


    public static void main(String[] args) {
        Scanner scanner = new Scanner(System.in);
        System.out.println("输入3科成绩：java，android，sql");
        int java = scanner.nextInt();
        int android = scanner.nextInt();
        int sql = scanner.nextInt();
        int maxScore = java;
        if(maxScore < android){
            maxScore = android;
        }
        if (maxScore < sql){
            maxScore = sql;
        }
        System.out.println("最大成绩为："+maxScore);

思路在于定义一个变量maxScore，经过比较，总是将最大值保存在该变量中，最后输出该变量即可
