java - compare two numeric String values

Question

I have a simple doubt. Would be great if anyone helps me.

I have two strings:

String string1 = "4"; // and 
String string2 = "04";

Both the values are equal but how to compare them in java? We have equals and equalsIgnoreCase for comparing String alpha values, similarly how to compare numeric values.

Answer 1

Integer.parseInt("4") == Integer.parseInt("04")

That is it. You can convert a numeric string into integer using Integer.parseInt(String) method, which returns an int type. And then comparison is same as 4 == 4.
