BiMap Interface
A BiMap is a special kind of map which maintains an inverse view of the map while ensuring that no duplicate values are present in the map and a value can be used safely to get the key back.
package org.fool.guava.collections; import com.google.common.collect.BiMap; import com.google.common.collect.HashBiMap; public class BiMapTest { public static void main(String[] args) { BiMap<Integer, String> empIDNameMap = HashBiMap.create(); empIDNameMap.put(new Integer(101), "Mahesh"); empIDNameMap.put(new Integer(102), "Sohan"); empIDNameMap.put(new Integer(103), "Ramesh"); System.out.println(empIDNameMap.inverse().get("Mahesh")); } }
output
101
