Declaration

Following is the declaration for java.lang.Character.isISOControl() method

public static boolean isISOControl(int codePoint)

Parameters

  • codePoint - the character (Unicode code point) to be tested

Return Value

This method returns true if the character is an ISO control character, false otherwise.

Exception

  • NA

Example

The following example shows the usage of lang.Character.isISOControl() method.

package com.tutorialspoint;

import java.lang.*;

public class CharacterDemo {

   public static void main(String[] args) {

      // create 2 int primitives cp1, cp2
      int cp1, cp2;

      // assign values to cp1, cp2
      cp1 = 0x008f;
      cp2 = 0x0123;

      // create 2 boolean primitives b1, b2
      boolean b1, b2;

      // assign isISOControl results of cp1, cp2 to b1, b2
      b1 = Character.isISOControl(cp1);
      b2 = Character.isISOControl(cp2);

      String str1 = "cp1 is an ISO control character is " + b1;
      String str2 = "cp2 is an ISO control character is " + b2;

      // print b1, b2 values
      System.out.println( str1 );
      System.out.println( str2 );
   }
}

Let us compile and run the above program, this will produce the following result:

cp1 is an ISO control character is true
cp2 is an ISO control character is false
