Check whether the entered value is whitespace or not in Java
To check whether the entered value is whitespace or not in Java, use the Character.isWhitespace() method.
We have a value to be checked.
char val = ' ';
Now let us use the Character.isWhitespace() method.
if (Character.isWhitespace(val)) {
System.out.println("Value is a Whitespace!");
} else {
System.out.println("Value is not a Whitespace");
}Let us see the complete example now to check whether the entered value is whitespace or not in Java.
Example
public class Demo {
public static void main(String []args) {
char val =' ';
System.out.println("Value: "+val);
if (Character.isWhitespace(val)) {
System.out.println("Value is a Whitespace!");
} else {
System.out.println("Value is not a Whitespace");
}
}
}Output
Value: Value is a Whitespace!
Let us see another example.
Example
public class Demo {
public static void main(String []args) {
char val ='L';
System.out.println("Value: "+val);
if (Character.isWhitespace(val)) {
System.out.println("Value is a Whitespace!");
}else {
System.out.println("Value is not a Whitespace");
}
}
}Output
Value: L Value is not a Whitespace
