Java Character toLowerCase(int codePoint) Method

Java toLowerCase(int codePoint) method is a part of Character class. This method converts the specified Unicode code point character argument to the lowercase using case mapping information which is provided by the Unicode Data file.

Syntax:

public static char toLowerCase(int codePoint) 

Parameters:

The parameter passed is the Unicode code point character value to be converted.

Returns:

Returns the lowercase equivalent of the specified character, if any; otherwise, the character itself.

Example 1:

Here, the specified code points are converted into its equivalent lowercase characters.

public class StudyTonight
{  
	public static void main(String[] args)
	{  
		int cp1 = 78;  
		int cp2 = 102;  
		int cp3 = 66;  
		int cp4 = 48;   
		int cp5 = 1232;  

		char ch1 = Character.toLowerCase((char)cp1);  
		char ch2 = Character.toLowerCase((char)cp2);  
		char ch3 = Character.toLowerCase((char)cp3);  
		char ch4 = Character.toLowerCase((char)cp4);  
		char ch5 = Character.toLowerCase((char)cp5);  

		System.out.println("The lowercase character is :"+ch1);  
		System.out.println("The lowercase character is :"+ch2); 
		System.out.println("The lowercase character is :"+ch3);  
		System.out.println("The lowercase character is :"+ch4);  
		System.out.println("The lowercase character is :"+ch5);  
	}  
}

The lowercase character is :n
The lowercase character is :f
The lowercase character is :b
The lowercase character is :0
The lowercase character is :?

Example 2:

Here is a user-defined example where anyone using this code can put a value of his choice and get the equivalent output.

import java.util.Scanner; 
public class StudyTonight
{  
	public static void main(String[] args)
	{  
		try
		{
			System.out.print("Enter the Unicode codepoint: ");  
			Scanner sc = new Scanner(System.in);         
			int cp = sc.nextInt();  
			char cc = Character.toLowerCase((char)cp);
			System.out.println("The lowercase character is : "+cc);
		}
		catch(Exception e)
		{
			System.out.println("Invalid Input!!");
		}
	}  
}

Enter the Unicode codepoint: 77
The lowercase character is : m
***************************************
Enter the Unicode codepoint: 100
The lowercase character is : d
