请用Java语言编程

import java.io.BufferedOutputStream;
import java.io.BufferedWriter;
import java.io.File;
import java.io.FileOutputStream;
import java.io.FileWriter;
import java.util.Scanner;

public class Test1 {
public static void main(String[] args) throws Exception {
//input
Scanner scanner = new Scanner(System.in);
String[][] ss = new String[2][3];
System.out.println("请输入,回车键控制输入一次的结束：");
for(int i=0;ifor(int j=0;jString str = scanner.next();
ss[i][j] = str;
}
}
//byte way
FileOutputStream outputStream = new FileOutputStream(new File("d:/test.txt"));
BufferedOutputStream buffer = new BufferedOutputStream(outputStream);
for(int i=0;ifor(int j=0;jbyte[] bs = ss[i][j].getBytes();
buffer.write(bs);
buffer.write("\n".getBytes());
}
}
buffer.flush();
buffer.close();

//char way
FileWriter writer = new FileWriter(new File("d:/test1.txt"));
BufferedWriter bufferWriter = new BufferedWriter(writer);
for(int i=0;ifor(int j=0;jbufferWriter.write(ss[i][j]);
bufferWriter.newLine();
}
}
bufferWriter.flush();
bufferWriter.close();
}
}

以上是两种方式写入文件

#import java.io.*;
class str throws FileNotFoundException{
int i;j;
String string[][]={{"a1","b2","c3"},{"A1","B2","C3"}};
void m(){
DataOutputStream ou=new DataOutputStream(new FileOutputStream("message.txt"));
for(i=0;i<2;i++){
for(j=0;j<3;j++){
ou.writeUTF(string[i][j]);
}
}
}
ou.close();
public static void main(String args[]){
m();
}
}
