Question

I trying to compare 2 strings in Java to determine if they are the same:

System.out.println("app version: "+ appversion + " latest version: "+ latestversion); 

if(!appversion.equals(latestversion))
{            
    System.out.println("not the same"); 
}

However this is giving me unexpected results given the outputs:

app version: v1.1.2 latest version: v1.1.2
not the same

I have used .replaceAll("\\s",""); to remove any whitespaces from the strings with no success.

There is probably a very obvious answer to this but can anyone tell me what i’m doing wrong?

Answer 1

Instead of .replaceAll() method, use trim() method to remove white space while comparing String variables.

change your code as follows as,

if(!appversion.trim().equals(latestversion.trim()))
{            
    System.out.println("not the same"); 
}
