03总结

这一周，建民哥给我们讲述了怎么使得代码可以变得简洁，方便阅读，

我还对上周进行的测试进行了第二阶段成功测试，代码部分如下：

import java.io.BufferedReader;

import java.io.BufferedWriter;

import java.io.File;

import java.io.FileInputStream;

import java.io.FileNotFoundException;

import java.io.FileReader;

import java.io.FileWriter;

import java.io.IOException;

import java.io.InputStreamReader;

import java.math.BigInteger;

import java.util.Scanner;

 

public class shuzu{

    public static void main(String[] args){

            Scanner sc=new Scanner(System.in);

            System.out.println("输入10个数");

            int num[]=new int[10];

            int sum=0;

            int sum1=0;

            for(int i=0;i<10;i++) {

                num[i]=sc.nextInt();

                if(num[i]>sum) {

                    sum=num[i];

                }

            }

            for(int i=0;i<10;i++) {

                sum1=num[i];

                for(int j=i+1;j<10;j++) {

                    sum1=sum1+num[j];

                    if(sum1>sum) {

                        sum=sum1;

                    }

                }

            }

            System.out.println("最大和为："+sum);

       }

 

    static String s="";

 

 

//    public static void main(String[] args) throws IOException {

//

//        chansheng();

//        read();

//        String[] rang=s.split("[^(-9--10-9)]");

//        BigInteger value=new BigInteger("0");

//        BigInteger sum=new BigInteger(String.valueOf(rang[0]));

//        for(int i=0;i<rang.length;i++) {

//            int a=value.compareTo(BigInteger.valueOf(0));

//            if(a==0||a==-1) {

//                value=new BigInteger(String.valueOf(rang[i]));

//            }else {

//                value.add(new BigInteger(String.valueOf(rang[i])));

//

//            }

//            if(sum.compareTo(value)==-1) {

//                sum=value;

//            }

//        }

//        System.out.println("最大值为："+sum);

//    }

 

 

    public static String read() throws IOException {

        FileInputStream fis =new FileInputStream("leitianyushishabi.txt");

        BufferedReader br =new BufferedReader(new InputStreamReader(fis));

        String temp=" ";

        while((temp = br.readLine())!=null) {

            s= s+temp +"\n";

        }

        fis.close();

        br.close();

 

        return s;

 

    }

 

 

    public static void chansheng() throws IOException {

        int n;

        System.out.println("请输入要产生的数量：");

        Scanner sc=new Scanner(System.in);

        n=sc.nextInt();

        File file1=new File("leitianyushishabi.txt");

        FileWriter out=new FileWriter(file1);

        BufferedWriter bw =new BufferedWriter(out);

        for(int i=0;i<n;i++) {

            int ran =(int) ((int) (Math.random()*100000000)-Math.random()*100000000);

            BigInteger a=new BigInteger(String.valueOf(ran));

            bw.write(String.valueOf(a)+" ");

        }

        bw.close();

    }
