Java: Output String Containing a Key Phrase

Question

I am hoping to understand how to extract words from a string that contain a key phrase.

Let's assume that the key phrase is "_01", what is a good method for outputting any word in the input sequence "panorder_01, panorder_02, disorder_01, forkorder_01, forkorder_02, forkorder_03" that contains the key phrase?

Answer 1

You can split first your string and use the contains method to check of the string contains "_01"

sample:

String s = "panorder_01, panorder_02, disorder_01, forkorder_01, forkorder_02, forkorder_03";
    String s2 [] = s.split(",");
    for(String s3 : s2)
    {
        if(s3.trim().contains("_01"))
            System.out.println(s3.trim());
    }

result:

panorder_01
disorder_01
forkorder_01
