In this article, we will discuss how to convert each individual characters inside a String into a lowercase character using String’s toLowerCase() method

1. String’s toLowerCase () method:

• This String method is used to convert invoking sequence/string into lowercase characters
• That’s all character present in string/sequence

1.1 Method Signature:

public String toLowerCase();

1.2 Returns:

• String converted to lowercase

2. Examples on toLowerCase() method:

2.1 Convert invoking String into Lowercase

StringToLowerCaseMethod.java

package in.bench.resources.string.methods;

public class StringToLowerCaseMethod {

	public static void main(String[] args) {

		// sample URL string
		String url = "BenchResources.Net";

		// convert all characters
		// present inside string into lower-case
		String lowerCase = url.toLowerCase();

		// print to console - converted lower-case string
		System.out.println("Converted lower-case is : "
				+ lowerCase);
	}
}

Output:

Converted lower-case is : benchresources.net
