String st1 = "userList[1].name"

You can use split() with a regEx in both, JavaScript and Java to perform the split operation using multiple delimiters.

Here is an example in JavaScript:

// JavaScript
"userList[0].name".split(/[\[\]]+/)[1] // 0

And a very similar approach in Java:

// Java
String string = "userList[0].name";
String result = st.split("[\\[\\]]")[1]; // 0

Assuming that you will have a consistent string structure.
