Returns a shallow copy of this HashMap instance: the keys and values themselves are not cloned.

Usage

From source file:MainClass.java

public static void main(String[] a) {

    HashMap map = new HashMap();
    map.put("key1", "value1");
    map.put("key2", "value2");
    map.put("key3", "value3");

    HashMap map2 = (HashMap) map.clone();
    System.out.println(map2);/*from w  w  w  .j a v  a2  s . c  o m*/
}

From source file:Main.java

public static void main(String[] a) {
    HashMap<String, String> map = new HashMap<String, String>();
    map.put("key1", "value1");
    map.put("key2", "value2");
    map.put("key3", "value3");

    HashMap map2 = (HashMap) map.clone();
    System.out.println(map2);/*from  ww  w  . jav  a 2  s.co m*/
}

From source file:Main.java

public static void main(String a[]) {
    HashMap hashMap = new HashMap();
    HashMap hashMap1 = new HashMap();

    hashMap.put(1, "One");
    hashMap.put(2, "Two");
    hashMap.put(3, "Three");
    System.out.println("Original HashMap : " + hashMap);

    hashMap1 = (HashMap) hashMap.clone();

    System.out.println("Copied HashMap : " + hashMap1);
}

From source file:Main.java

public static void main(String args[]) {
    // create two hash maps

    HashMap<Integer, String> newmap1 = new HashMap<Integer, String>();
    HashMap<Integer, String> newmap2 = new HashMap<Integer, String>();

    // populate hash map
    newmap1.put(1, "tutorials");
    newmap1.put(2, "from");
    newmap1.put(3, "java2s.com");

    // clone 1st map
    newmap2 = (HashMap) newmap1.clone();

    System.out.println("1st Map: " + newmap1);
    System.out.println("Cloned 2nd Map: " + newmap2);
