Java Character isISOControl(char ch) Method

Java isISOControl(char ch) is a part of Character class. This method is used to check whether the specified character is an ISO control character or not.

A character is an ISO control character if its code lies in the range of '\u000' through '\u001F' or in the range of '\u007F' through '\u009F'.

Syntax:

public static boolean isISOControl(char ch)

Parameters:

The parameter passed is the character to be checked for ISO Control.

Returns:

Returns the boolean value true if the specified character is an ISO control character else return false.

Example 1:

Here, the characters are checked by using the isISOControl() method whether they are ISO Control characters or not.

public class StudyTonight
{  
	public static void main(String[] args)
	{  
		char ch1 = 'g';  
		char ch2 = 'D';  
		char ch3 = '#';  
		char ch4  = 'e';   
		char ch5  = '8';  

		boolean b1 = Character.isISOControl(ch1);  
		boolean b2 = Character.isISOControl(ch2);  
		boolean b3 = Character.isISOControl(ch3);  
		boolean b4 = Character.isISOControl(ch4);  
		boolean b5 = Character.isISOControl(ch5);  

		System.out.println(ch1 +" is a ISO control?:  "+b1);  
		System.out.println(ch2 +" is a ISO control?:  "+b2);  
		System.out.println(ch3 +" is a ISO control?:  "+b3);  
		System.out.println(ch4 +" is a ISO control? : "+b4);  
		System.out.println(ch5 +" is a ISO control?:  "+b5);  
	}  
} 


g is a ISO control?: false
D is a ISO control?: false
# is a ISO control?: false
e is a ISO control? : false
8 is a ISO control?: false

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 character: ");  
			Scanner sc = new Scanner(System.in);         
			char ch = sc.next().charAt(0);  
			boolean b = Character.isISOControl(ch);
			System.out.println(ch + " is an ISO Control? : "+b);
		}
		catch(Exception e)
		{
			System.out.println("Invalid Input!!");
		}
	}  
}  


Enter the character: ~
~ is an ISO Control? : false
**********************************
Enter the character: .
. is an ISO Control? : false
