Question

I have requirement of selecting s subset of data from a collection using a part of a key word

Assume that I have a collection consist of following entries,

"Pine Grosbeak"  
"House Crow"  
"Hume`s Leaf Warbler"  
"Great Northern Loon"  
"Long-tailed Duck"  
"Lapland Longspur"  
"Northern Gannet"  
"Eastern Imperial Eagle"  
"Little Auk"  
"Lesser Spotted Woodpecker"  
"Iceland Gull" 

When I provide a search string as “ro” following should be filtered;

"House Crow"  
"Pine Grosbeak"  

(This is something similar to “LIKE ‘%ro%’ “ clause in SQL)

Can some one help me on this?

Answer 1

You could simply do something like that:

for (String s : strings)
{
    if (s.contains(search))
    {
        // match
    }
}

And if you want to be case insensitive:

String lowerSearch = search.toLowerCase();  
for (String s : strings)
{
    if (s.toLowerCase().contains(lowerSearch))
    {
        // match
    }
}
