treemap get key and valuejava code example

Example 1: TreeMap V get(Object key) method in java

import java.util.TreeMap;
public class TreeMapGetObjectMethodExample
{
   public static void main(String[] args)
   {
      TreeMap<Integer, String> tm = new TreeMap<Integer, String>();
      tm.put(2, "tejas");
      tm.put(1, "om");
      tm.put(3, "tarun");
      tm.put(6, "siddarth");
      tm.put(5, "fanindra");
      System.out.println("Check value of key 5: ");
      System.out.println("Value is: " + tm.get(5));
   }
}

Example 2: TreeMap keySet() method in java

import java.util.TreeMap;
public class TreeMapKeySetMethodExample
{
   public static void main(String[] args)
   {
      TreeMap<Integer, String> tm = new TreeMap<Integer, String>();
      tm.put(53, "mango");
      tm.put(62, "apple");
      tm.put(29, "grapes");
      tm.put(93, "banana");
      tm.put(98, "watermelon");
      System.out.println("Given TreeMap is: " + tm);
      // use keySet() to get set view of keys
      System.out.println("set is: " + tm.keySet());
   }
}
