Java: Search a value in a Tree Map

Last update on March 12 2025 13:34:08 (UTC/GMT +8 hours)

Write a Java program to search for a value in a Tree Map.

Sample Solution:-

Java Code:

import java.util.*;  
public class Example4 {  
   public static void main(String args[]){  
  
  // Create a tree map
   TreeMap<String,String> tree_map1=new TreeMap<String,String>();      
  
  // Put elements to the map 
  tree_map1.put("C1", "Red");
  tree_map1.put("C2", "Green");
  tree_map1.put("C3", "Black");
  tree_map1.put("C4", "White"); 
    
 if(tree_map1.containsValue("Green")){
            System.out.println("The TreeMap contains value Green");
        } else {
            System.out.println("The TreeMap does not contain value Green");
        }
        if(tree_map1.containsValue("Pink")){
            System.out.println("The TreeMap contains value Pink");
        } else {
            System.out.println("The TreeMap does not contain value Pink");
        }
    }
}

Sample Output:

The TreeMap contains value Green                                       
The TreeMap does not contain value Pink

• Write a Java program to check if a TreeMap contains a specified value using containsValue() and print the outcome.
• Write a Java program to iterate over the values in a TreeMap to find a target value and print its corresponding key.
• Write a Java program to use Java streams to search for a value in a TreeMap and collect the matching entry.
• Write a Java program to implement a custom method that searches for a value in a TreeMap and returns the key if found.
