I was wondering, is there any way to change "5" into 5?

Char to integer
I am sure there must be an easier way, but one way for a single digit is
"0123456789".indexOf("5");
Look at the API, specifically the Integer class:
Javadocs Integer
Look up the parseInt() method
The following methods return 0, when the given char/String is no pure Number, else (of course) the given Number. :)
public static int getInt(char ch)
{
return getInt(new String(new char[]{ch}));
}
public static int getInt(String T)
{
try
{
return Integer.parseInt(T);
}
catch(Exception e){return 0;}
}
