String to integer

[Guest_imported]

Hi, I am new to Java and have an assignment where I have to set each character of a 4-character string to an integer (result 4 integers. It seems whatever I try doesn't work or I get (Unicode?) something like this, one position of my String has 0 my result is '48', my string has 1 my result is '49'. All I want is String 1 to become integer 1. I know this must be a snap, but I cannot seem to gleen it out of my text book or JDK documentation.

Thanks

Hi,

There are a lot of ways you can change a String to an int value. For exampe:-

String abc = "123";
int temp = Integer.parseInt(abc);

The value of temp would be 123. However, to be sure that the String is always an int value, we will need the try and catch statement. So if your String happens to be "abc" instead of "123", the line "Invalid String." would be printed out to the console.

try
{
String abc = "123";
int temp = Integer.parseInt(abc);
}
catch (NumberFormatException e)
{
System.out.println("Invalid String."
}
