I am passing the following to this code Howard James Mike. I am trying to read Howard but it is not working Why..

PART THAT DOES NOT WORK
if (myout == "Howard")
{
System.out.println("Hey Howardppp");
}

ENTIRE CODE
public class MyTest {

/**
* @param args
*/
public static void main(String[] args) {
// TODO Auto-generated method stub

int howmany = args.length;
String[] myInfo = new String[howmany];

for (int a = 0 ; a < howmany; a++)
{
myInfo[a] = args[a]; //"Howard";
}

System.out.println(" how many args " + howmany);

for (int i = 0 ; i < howmany; i++)
{
System.out.println("Item" + i + " " + myInfo[i]);

String myout;
myout = myInfo[i];
// this part does not work why
if (myout == "Howard")

System.out.println("Hey Howardppp");
}
//System.out.println("myout=" + myout);
}

System.out.println("end");

}

Hi

The classic beginner mistake. == checks equality of pointers. Use String.equals() to check equality of values :

CODE --> (fragment)

if (myout.equals("Howard")) {
  System.out.println("Hey Howardppp");
}

// or with null-safe Yoda condition
if ("Howard".equals(myout)) {
  System.out.println("Hey Howardppp");
}

Next time please indent your code and post it between [code] and [/code] TGML tags.

Feherke.
