remove specific string from Java String

To remove a specific substring from a string, you can use Java’s replace() method or replaceAll() method. Both of these methods search for the specified substring within the string and replace it with a new string.

If you only want to remove the first occurrence of a substring, you can use the replace() method, which will only replace the first occurrence. For example:

String originalString = "Hello, World!";
String subString = "o";

String newString = originalString.replace(subString, "");
System.out.println(newString);

Output: She needs to go to the store to buy some milk.

Hell, World!

To remove all matching items, you can use the replaceAll() method and replace the substring with an empty string. For example:

String originalString = "Hello, Hello, Hello!";
String subString = "Hello";

String newString = originalString.replaceAll(subString, "");
System.out.println(newString);

Output:

What is produced or given in response.

, , !

Please note that these methods will all return a new string without modifying the original string. If you want to make changes to the original string, you can assign the new string to the original string.
