小型的java编译器GUI

java代码 通过java的Swing进行GUI开发 采用树形目录对java文件进行组织 可以实行对java文件的增加、修改、删除以及运行 类似于简易版的eclipse

import java.util.ArrayList;
import java.util.List;
import java.util.Scanner;

public class Main_Excel {
	//通过参考百度到的代码完成
    public static void main（String[] args） {
    	try {
			   ReadExcel excel = new ReadExcel（）;
    	List list = new ArrayList（）;
    	list = excel.readExcel（“source_Excel/student_info.xls“）;
    	System.out.println（“Current number of people:“）;
    	for（int i = 0 ; i < list.size（） ; i++）{
    		System.out.println（list.get（i）.Value（））;
    	}
    	List list1 = new ArrayList（）;
    	int i = 0;
    	Scanner sc = new Scanner（System.in）;
    	System.out.println（“Please enter the number of people to insert:“）;
    	int j = sc.nextInt（）;
    	System.out.println（“Please enter - Student ID - Name - Age - Results:“）;
    	String[] str = new String [4];
    	String str1 = null;
    	while（i < j）{
    		sc = new Scanner（System.in）;
    		StudentBean student = new StudentBean（）;
    		str1 = sc.nextLine（）;
    		str = str1.split（“\\s+“）;
        	student.setNo（str[0].trim（））;
        	student.setName（str[1].trim（））;
        	student.setAge（str[2].trim（））;
        	student.setScore（str[3].trim（））;
        	list1.add（student）;
    		i++;
    	}
    	sc.close（）;
    	WriteExcel writeExcel = new WriteExcel（list1）;
    	writeExcel.Insert（）;
    	list = excel.readExcel（“source_Excel/student_info.xls“）;
    	System.out.println（“Insert the following table:“）;
    	for（i = 0 ; i < list.size（） ; i++）{
    		System.out.println（list.get（i）.Value（））;
    	}
		} catch （Exception e） {
			e.printStackTrace（）;
		}

    }
    
}
