Method Detail

parseInt

public static int parseInt(java.lang.String str,
           int defaultValue)

This method parses an integer from the string. If the string does not properly parse to an int, the default value it used. This avoids throwing an exception which is expenses as far as processing.

Parameters:

strInt -

defaultValue -

Returns:

parseInt

public static int parseInt(java.lang.String s,
           int radix,
           int defaultValue,
           boolean onErrorUseDefault)

This performs a similar parse to int as Integer.parseInt(String, int) where the int is the radix. The difference is that when it encounters and error, this method will return the default value instead of throwing an exception, and this will trim the string prior to converting. The calling method can then check for the default value and assume an error in parsing without encurring the overhead of the exception processing

Parameters:

s -

radix -

defaultValue -

Returns:

Throws:

java.lang.NumberFormatException
