Returns the value to which the specified key is mapped, or null if this map contains no mapping for the key.

Usage

From source file:Main.java

public static void main(String[] argv) throws Exception {
    final int MAX_ENTRIES = 100;
    Map cache = new LinkedHashMap(MAX_ENTRIES + 1, .75F, true) {
        public boolean removeEldestEntry(Map.Entry eldest) {
            return size() > MAX_ENTRIES;
        }//from   w ww  . j  a  va 2  s  .c  o  m
    };

    Object key = "key";
    Object value = "value";
    cache.put(key, value);
    Object o = cache.get(key);
    if (o == null && !cache.containsKey(key)) {
    }
    cache = (Map) Collections.synchronizedMap(cache);
