Search a String Array in Java?

Question

How do I search a string array with start with keyword?

for example,

String[] str = { "abcd", "abdc", "bcda"};

when my search string is "a" it must show

abcd and abdc

when my search string is "abc" then it should be "abcd".

You loop over the array and compare the beginning of each entry with your search string. What have you tried? Show some code. — RoToRa

Is it sorted. And is there any reason you can't use something other than an array, like a TreeList? — sblundy

String[] strArray = {"abcd", "abdc", "bcda"};
for (String s : strArray)
    if (s.startsWith(searchTerm))
        System.out.println(s);

Swap startsWith for contains you wish to simply look for containment.

I agree, but just a side note that this is a case sensitive operation.

good point. Do s.toLowerCase().startsWith(searchTerm.toLowerCase()) to make it insensitive.
