Application Security Testing: An Integral Part of DevOps

String Search Mechanism

How do I do a string comparison where I want to determine if one string is contained within another? For example:
Str1 = "Degree in IT";
Str2 = "Diploma or Degree in IT";
I want to see if Str1 is contined in Str2.

The String class supports this type of comparison through its indexOf(String) method. The method will return the start index of the first occurrence of the substring or -1 if the substring does not occur within the String object.

More general pattern matching can be performed with a third-party regular expression package.
