Can someone help please?
I just started the J2SE online training cource.
I have a problem with the homework part in the control structure
section.The homework is to modify the MyForLoopProject project and use
the while loop.
The code works correctly if you type a valid name listed in the array.
When you type an name not listed in the array I get an error...instead
of displaying ("noname" is not found)
Error:
Exception in thread "main" java.lang.ArrayIndexOutOfBoundsException:
8
at MyOwnWhile.main(MyOwnWhile.java:26)
Java Result: 1
BUILD SUCCESSFUL (total time: 6 seconds)
Code:
import javax.swing.JOptionPane;
public class MyOwnWhile {
/** Creates a new instance of MyOwnWhile */
public MyOwnWhile() {
}
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
// Declare and initialize String array variable called names.
String names []=
{"Beah","Bianca","Lance","Belle","Nico","Yza","Gem","Ethan"};
// This is the search string we are going to use to search the
array.
String searchName = JOptionPane.showInputDialog("Enter either
\"Yza\" or \"noname\"!");
// Declare and initialize boolean primitive type variable
calld foundName.
boolean foundName =false;
int i=0;
while (i<names.length){
i++;
if (names [i ].equals(searchName)){
foundName =true;
break;
}
}
// Display the result
if (foundName)
JOptionPane.showMessageDialog(null, searchName + " is
found!");
else
JOptionPane.showMessageDialog(null, searchName + " is not
found!");
}
}
