Remove Special Character From a String in Java

Hey, Welcome to the Practice House. In this post, we will learn how to Remove special Character from a string in java. We will also learn how to join the split String in Java.

In our scenario, we got hyphen in our String So to remove this hyphen we can use the split() method. If you have any complex special Character please use RegEx. Please visit their official website to learn more about RegEx.

package com.practicehouse.examplePrograms;

import java.util.Arrays;

public class SplitAndJoin {

	public static void main(String[] args) {
		
		String accountNumber =  "125-0987897-876";
		
		String[] words = accountNumber.split("-");
		
		System.out.println("After Splitted :" + Arrays.toString(words));
		
		accountNumber = String.join("", words);
		
		System.out.println("Finally our Account Number: " + accountNumber);

	}

}

package com.practicehouse.examplePrograms;

import java.util.Arrays;

public class SplitAndJoin {

public static void main(String[] args) {

String accountNumber = "125-0987897-876";

String[] words = accountNumber.split("-");

System.out.println("After Splitted :" + Arrays.toString(words));

accountNumber = String.join("", words);

System.out.println("Finally our Account Number: " + accountNumber);

}

Sample Output:

Account Number : 125-0987897-876
After Splitted :[125, 0987897, 876]
Finally our Account Number: 1250987897876

Account Number : 125-0987897-876

After Splitted :[125, 0987897, 876]

Finally our Account Number: 1250987897876
