isLetterOrDigit() method in Java
The isLetterOrDigit() method in Java returns TRUE if the entered value is a letter or digit.
We have the following character.
char val ='P';
Now, let us check for letter or digit using if-else decision-making statement.
if (Character.isLetterOrDigit(val)) { System.out.println("Value is a letter or digit!"); } else { System.out.println("Value is neither a letter nor a digit!"); }
The following is an example.
Example
public class Demo { public static void main(String []args) { char val ='P'; System.out.println("Value: "+val); if (Character.isLetterOrDigit(val)) { System.out.println("Value is a letter or digit!"); } else { System.out.println("Value is neither a letter nor a digit!"); } } }
Output
Value: P Value is a letter or digit!
Let us see another example.
Example
public class Demo { public static void main(String []args) { char val ='^'; System.out.println("Value: "+val); if (Character.isLetterOrDigit(val)) { System.out.println("Value is a letter or digit!"); }else { System.out.println("Value is neither a letter nor a digit!"); } } }
Output
Value: ^ Value is neither a letter nor a digit!
