Java Trim String

VinylJunkie

Please help this is annoying me. Ive a string which I got from a combobox (.getSelectedItem()) ive assigned it to a string variable, However I only want the first letter of the string.

Can I use some sort of Left() function to do this?

strName.substring(0,1) I think

you can use .substring(int start,int end):

so .substring(0,1);

See String API at http://java.sun.com/j2se/1.5.0/docs/api/

use charAt(0) to get the leftmost character in the String

charAt

public char charAt(int index)

Returns the char value at the specified index. An index ranges from 0 to length() - 1. The first char value of the sequence is at index 0, the next at index 1, and so on, as for array indexing.

If the char value specified by the index is a surrogate, the surrogate value is returned.

Specified by:
charAt in interface CharSequence

Parameters:
index - the index of the char value.
Returns:
the char value at the specified index of this string. The first char value is at index 0.
Throws:
IndexOutOfBoundsException - if the index argument is negative or not less than the length of this string.

The only potential problem with this is that it returns a char as opposed to a String, but it could be the one for the job, depending on what the op is looking for.

Java is case sensitive! The method is called substring not subString!
