~~具体的题目是真的记不清了...~~

题1

利用随机函数产生30个学生的课程成绩（30~100）存入数组中。每行输入6个，输出所有符合要求的素数，要求每行输出4个，并输出素数的总数目。

import java.util.ArrayList;
import javax.print.attribute.PrintRequestAttributeSet;
import acm.program.ConsoleProgram;public class Test01 extends ConsoleProgram { public void run() {ArrayList<Integer>sq = new ArrayList<>();sq.add(55);	sq.add(96);sq.add(39);	sq.add(23);sq.add(56);	sq.add(43);//第一行sq.add(30);	sq.add(99);sq.add(99);	sq.add(82);sq.add(34);	sq.add(48);//第二行sq.add(48);	sq.add(18);sq.add(86);	sq.add(50);sq.add(76);	sq.add(67);//第三行sq.add(23);	sq.add(76);sq.add(28);	sq.add(97);sq.add(95);	sq.add(26);//第四行sq.add(89);	sq.add(13);sq.add(70);	sq.add(81);sq.add(24);	sq.add(34);//第五行int x,sum;x=0;sum=0;for(int i=0; i<sq.size(); i++) {if(pan(sq.get(i))) {sum++;x++;if(x<4)  print(sq.get(i)+" ");else {x=0;println(sq.get(i)+" ");}	}}println();println("它们的总数是"+sum);}public boolean pan(int x) {//判断素数if(x==2)	return true;else {for(int i=2; i<x; i++){if(x%i==0)	return false;}}return true;}
}

生成如下界面，符合题目要求的文件

package t02.test; 
import java.awt.event.ActionEvent;
import java.io.BufferedReader;
import java.io.FileNotFoundException;
import java.io.FileReader;
import java.io.IOException;
import javax.swing.JButton;
import javax.swing.JLabel;
import javax.swing.JTextField;
import acm.program.ConsoleProgram;public class Test03 extends ConsoleProgram 
{JTextField qv=null;public void init() {setSize(300,400);setTitle("文件拷贝 XX");JLabel sq = new JLabel("文件名:");JLabel sp = new JLabel("文件内容:");qv = new JTextField(10);JButton v = new JButton("拷贝");add(sq, NORTH);add(qv, NORTH);add(sp, WEST);add(v, SOUTH);addActionListeners();}public void actionPerformed(ActionEvent e) {String a = qv.getText();try {BufferedReader po = new BufferedReader(new FileReader(a));String q = po.readLine();String[] str = q.split(":");print("ID:"+str[0]+"成绩");println(str[1]);} catch(FileNotFoundException e1) {// TODO Auto-generated catch blocke1.printStackTrace();} catch(IOException e1) {// TODO Auto-generated catch blocke1.printStackTrace();}}
}

}

}
