StringUtils replaceEach() Example

StringUtils replaceEach() Example | In this blog we will discuss the replaceEach() method of StringUtils class. This method is used to replace each of the characters present in the string.

The question might arise what is the difference between replace() and replaceEach() method? The replace() method replaces all the occurrences of the given pattern provided the pattern should be in the same order as in the string and replace accepts only one string whereas replaceEach() accepts the array of strings. Also replaceEach() can replace the occurrence of the given pattern provided it does not need to be the same as in the string.

StringUtils replaceEach() Method Syntax

The syntax for the replaceEach() method is as follows:-
public static String replaceEach(final String text, final String[ ] searchList, final String[ ] replacementList)
Parameters:
text: the original string.
searchList: array of strings that contains the pattern to be replaced.
replacementList: array of the strings that have the string to be placed at a particular position.

Java StringUtils replaceEach() Example

import org.apache.commons.lang3.StringUtils;

public class Main {
    public static void main(String[] args) {
        String str = "7896";
        System.out.println("The string after the replacement is: "
                + StringUtils.replaceEach(str, new String[] { "789" }, new String[] { "156" }));
        str = " ";
        System.out.println("The string after the replacement is: "
                + StringUtils.replaceEach(str, new String[] { "789" }, new String[] { "123" }));
    }
}

Output:-

The string after the replacement is: 1566
The string after the replacement is:

import org.apache.commons.lang3.StringUtils;

public class Main {
    public static void main(String[] args) {
        String str = "abc";
        System.out.println("The string after the replacement is: "
                + StringUtils.replaceEach(str, new String[] { " " }, new String[] { " " }));
        str = "abc";
        System.out.println("The string after the replacement is: "
                + StringUtils.replaceEach(str, new String[] { "789" }, new String[] {}));
    }
}

Output:-

The string after the replacement is: abc
The string after the replacement is: abc

import org.apache.commons.lang3.StringUtils;

public class Main {
    public static void main(String[] args) {
        String str = "abc";
        System.out.println("The string after the replacement is: "
                + StringUtils.replaceEach(str, new String[] { "a" }, new String[] { " " }));
        str = "abc";
        System.out.println("The string after the replacement is: "
                + StringUtils.replaceEach(str, new String[] { "789" }, new String[] { "123" }));
        str = "abcde";
        System.out.println("The string after the replacement is: "
                + StringUtils.replaceEach(str, new String[] { "a", "d" }, new String[] { "A", "D" }));
    }
}

Output:-

The string after the replacement is: bc
The string after the replacement is: abc
The string after the replacement is: AbcDe
