Regarding Exception

Hi friend,


public class ExceptionTest{
public ExceptionTest(String aName, double aSpeed) {
if ( !textHasContent(aName) ) {
throw new IllegalArgumentException("Name has no content.");
}
if (aSpeed < 0.0 || aSpeed > 1.0) {
throw new IllegalArgumentException("Speed not in range [0..1]: " + aSpeed);
}
fName = aName;
fSpeed = aSpeed;
}
private String fName;
private double fSpeed;
private boolean textHasContent(String text){
String EMPTY_STRING = "";
return (text != null) && (!text.trim().equals(EMPTY_STRING));
}
public static void main(String args[]){
System.out.println("Welcome to Roseindia.");
}
}
