Is it possible to test the first few chars of a string

BrokenArrows

Just windering if it is possible to test the first few chars of a string

eg

String a = "user john";

If(first 4 chars is "user")
System.out.println(print out "john");


the above string is likely to be sent down from a class or something not sure yet.

Slaanesh

if(a.startsWith("user "))
System.out.println(a.substring(5,a.length()));

Or thereabouts.

works like a charm thanks.

One more thing.


If the string is passed down as "user John something"

Can i print out Just john. ie print until a space is reached.

Slaanesh

String a = "user john soimethingssdffs";

	if(a.startsWith("user "))
	{
		if(a.lastIndexOf(" ") >5)
		{
			System.out.println(a.substring(5,a.lastIndexOf(" ")));
		}
		else
		{
			System.out.println(a.substring(5,a.length()));
		}
	}

Note: If you have "user john something something"

The result will be "john something"

You could check up to the second space only if need be.

Just look at the example involving the .split() method in the String class - StringTokenizer is deprecated, so best not get into the habit of using it if they're going to pull it.
