ArrayList contains case sensitivity

Question

I am currently using the contains method belonging to the ArrayList class for making a search. Is there a way to make this search case insensitive in java? I found that in C

Don't reinvent the wheel. Use well tested APIs. For your purpose use Apache Commons StringUtils.

From the Javadoc: Compares given string to a CharSequences vararg of searchStrings returning true if the string is equal to any of the searchStrings, ignoring case.

import org.apache.commons.lang3.StringUtils;
...
StringUtils.equalsAnyIgnoreCase(null, (CharSequence[]) null) = false
StringUtils.equalsAnyIgnoreCase(null, null, null)    = true
StringUtils.equalsAnyIgnoreCase(null, "abc", "def")  = false
StringUtils.equalsAnyIgnoreCase("abc", null, "def")  = false
StringUtils.equalsAnyIgnoreCase("abc", "abc", "def") = true
StringUtils.equalsAnyIgnoreCase("abc", "ABC", "DEF") = true
