Answer 1

for completeness using google-collections/guava:

import com.google.common.collect.Sets;

static final Set fruit = Sets.newHashSet("APPLE", "ORANGES", "GRAPES");

if (fruit.contains(fruitname))

or using the plane old jdk classes:

static final Set fruit = new HashSet(Arrays.asList("APPLE", "ORANGES", "GRAPES"));
