浅谈java 数据处理(int[][]存储与读取)

MyFile .java：

import java.io.BufferedReader;

import java.io.File;

import java.io.FileReader;

import java.io.FileWriter;

public class MyFile {

public static void SaveFile(String filename,int[][] arr){

try {

File file = new File(filename); //存放数组数据的文件

FileWriter out = new FileWriter(file); //文件写入流

try {

getRecord(out,arr);

} catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

out.close();

} catch (Exception ex) {

ex.printStackTrace();

}

}

private static void getRecord(FileWriter out,int[][] arr)

throws Exception {

//将数组中的数据写入到文件中。每行各数据之间TAB间隔

for(int i=0;i

for(int j=0;j

out.write(arr[i][j]+"\t");

}

out.write("\r\n");

}

}

public static void ReadFile(String filename,int[][] arr2){

try {

File file = new File(filename); //存放数组数据的文件

BufferedReader in = new BufferedReader(new FileReader(file)); //

try {

readRecord(in,arr2);

} catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

in.close();

} catch (Exception ex) {

ex.printStackTrace();

}

}

private static void readRecord(BufferedReader in,int[][] arr2)

throws Exception {

String line; //一行数据

int row=0;

//逐行读取，并将每个数组放入到数组中

while((line = in.readLine()) != null){

String[] temp = linehttp://.split("\t");

for(int j=0;j

// arr2[row][j] = Double.parseDouble(temp[j]);

arr2[row][j] = Integer.parseInt(temp[j]);

}

row++;

}

}

}

使用：

public static int imagedate[ ][ ];

MyFile.SaveFile("d:\\array.txt",imagedate);

for(int j=0;j

out.write(arr[i][j]+"\t");

}

out.write("\r\n");

}

}

public static void ReadFile(String filename,int[][] arr2){

try {

File file = new File(filename); //存放数组数据的文件

BufferedReader in = new BufferedReader(new FileReader(file)); //

try {

readRecord(in,arr2);

} catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

in.close();

} catch (Exception ex) {

ex.printStackTrace();

}

}

private static void readRecord(BufferedReader in,int[][] arr2)

throws Exception {

String line; //一行数据

int row=0;

//逐行读取，并将每个数组放入到数组中

while((line = in.readLine()) != null){

String[] temp = linehttp://.split("\t");

for(int j=0;j

// arr2[row][j] = Double.parseDouble(temp[j]);

arr2[row][j] = Integer.parseInt(temp[j]);

}

row++;

}

}

}

使用：

public static int imagedate[ ][ ];

MyFile.SaveFile("d:\\array.txt",imagedate);

out.write(arr[i][j]+"\t");

}

out.write("\r\n");

}

}

public static void ReadFile(String filename,int[][] arr2){

try {

File file = new File(filename); //存放数组数据的文件

BufferedReader in = new BufferedReader(new FileReader(file)); //

try {

readRecord(in,arr2);

} catch (Exception e) {

// TODO Auto-generated catch block

e.printStackTrace();

}

in.close();

} catch (Exception ex) {

ex.printStackTrace();

}

}

private static void readRecord(BufferedReader in,int[][] arr2)

throws Exception {

String line; //一行数据

int row=0;

//逐行读取，并将每个数组放入到数组中

while((line = in.readLine()) != null){

String[] temp = linehttp://.split("\t");

for(int j=0;j

// arr2[row][j] = Double.parseDouble(temp[j]);

arr2[row][j] = Integer.parseInt(temp[j]);

}

row++;

}

}

}

使用：

public static int imagedate[ ][ ];

MyFile.SaveFile("d:\\array.txt",imagedate);

// arr2[row][j] = Double.parseDouble(temp[j]);

arr2[row][j] = Integer.parseInt(temp[j]);

}

row++;

}

}

}

使用：

public static int imagedate[ ][ ];

MyFile.SaveFile("d:\\array.txt",imagedate);
