Example

The following example shows the usage of lang.Character.isLowerCase() 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 = 0x007a;
      cp2 = 0x0fff;

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

      /**
       *  check if cp1, cp2 represents lowercase characters
       *  and assign results to b1, b2
       */
      b1 = Character.isLowerCase(cp1);
      b2 = Character.isLowerCase(cp2);

      String str1 = "cp1 represents a lowercase character is " + b1;
      String str2 = "cp2 represents a lowercase 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 represents a lowercase character is true
cp2 represents a lowercase character is false
