title: Is there Pandas DataFrame equivalent in Java?
body: <p>I am using Python Pandas dataframes to load JSON file in and directly apply several calculation in DF and print out output as JSON.</p>
  
  <p>Now need to port logic to Java.</p>
  
  <p>Is there a Panadas DataFrame equivalent in Java so that can load same JSON file in it and do similar DataFrame calculations (e.g. add column, make first + second column = third column etc.)</p>
  
  <p>Thanks.</p>
