Java endsWith() Method Example

Hello Readers…

In this article we will learn the use of endsWith()  method in java, for that we will see the below example in which we have to find out zip file in the given path and if zip file is present then unzip it and display the name of files and total number of files which is present in zip files. In this example I have created a folder Tutorial in my E:\\Tutorial drive in which there are 2 zip file present zipFile1.zip and zipFile2.zip and each zip contains four text file i.e., file1.txt , file2.txt, file3.txt and file4.txt . See below example…

package com.ma3.common;

import java.io.BufferedInputStream;

import java.io.File;

import java.io.FileInputStream;

import java.io.FileNotFoundException;

import java.io.IOException;

import java.util.ArrayList;

import java.util.List;

import java.util.zip.ZipEntry;

import java.util.zip.ZipInputStream;

public class TheTechMatin {

     public static void findZipIn(String zipFilePath) {

          

           File zipFile = new File(zipFilePath);

           String[] files = zipFile.list();

           String zipFileName=null;

           int zipCount=0;

           List<String> listOfZipFiles =new ArrayList<>();

           if(files != null) {

                for (String file : files) {

                   if(file != null) {

                    if (file.endsWith(".zip")) {

                    zipCount++;

                    zipFileName=file;

                    listOfZipFiles.add(zipFileName);

                    System.out.println("Zip File Name : "+zipFileName);

                                                    System.out.println("=========================");

                               

                                //custom method

                            unzipFile(zipFilePath+"/"+file, zipFileName);

                           }   

                     }

                }

System.out.println("Total"+zipCount+" Zip Files Found "+ listOfZipFiles);

           }

           else {

                System.out.println("File Not Found : "+ zipFilePath);

           }

     }

     public static void unzipFile(String zipFile, String zipFileName) {

           //extract zip file and display name of files present in zip

           FileInputStream fis = null;

        ZipInputStream zipIs = null;

        ZipEntry zEntry = null;

        int count=0;

        try {

            fis = new FileInputStream(zipFile);

            zipIs = new ZipInputStream(new BufferedInputStream(fis));

            while((zEntry = zipIs.getNextEntry()) != null){

                count++;

                System.out.println(count+". "+zEntry.getName());

            }

 System.out.println("Total : "+count+" Files Found In "+zipFileName);

            System.out.println("=========================");

            zipIs.close();

        } catch (FileNotFoundException e) {

            e.printStackTrace();

        } catch (IOException e) {

            e.printStackTrace();

        }

     }

     public static void main(String[] args) {

           String pathStr = "E:\\Tutorial";

           findZipIn(pathStr);

     }

}

output

Zip File Name : zipFile1.zip

=========================

1. ZipFile/file1.txt

2. ZipFile/file2.txt

3. ZipFile/file3.txt

4. ZipFile/file4.txt

Total : 4 Files Found In zipFile1.zip

=========================

Zip File Name : ZipFile2.zip

=========================

1. ZipFile/file1.txt

2. ZipFile/file2.txt

3. ZipFile/file3.txt

4. ZipFile/file4.txt

Total : 4 Files Found In ZipFile2.zip

===================================

Total 2 Zip Files Found [zipFile1.zip, ZipFile2.zip]
