decompile error

[zew13]

I decompile instargram

public static boolean isNullOrEmpty(String paramString)
{
if ((paramString == null) || (paramString.length() == 0));
for (int i = 1; ; i = 0)
return i;
}

i think , this should

public static boolean isNullOrEmpty(String paramString)
{
return ((paramString == null) || (paramString.length() == 0));
}
