# Java HashMap values() Method
[ Java HashMap](#)
The values() method returns a Set view of all the values contained in the mapping.
The syntax for the values() method is:
hashmap.values()
**Note:** hashmap is an object of the HashMap class.
**Parameter Description:**
* None
### Return Value
Returns a collection view of all the value values in the HashMap.
### Example
The following example demonstrates the use of the values() method:
## Example
import java.util.HashMap;
class Main {
public static void main(String[] args){
// Create a HashMap
HashMap sites =new HashMap();
// Add some elements to the HashMap
sites.put(1, "Google");
sites.put(2, "");
sites.put(3, "Taobao");
System.out.println("sites HashMap: "+ sites);
// Return a view of all value values
System.out.println("Values: "+ sites.values());
}
}
The output of the above program is:
sites HashMap: {1=Google, 2=, 3=Taobao}Values: [Google, , Taobao]
The values() method can be used with a for-each loop to iterate over all the values in the HashMap.
## Example
import java.util.HashMap;
class Main {
public static void main(String[] args){
// Create a HashMap
HashMap sites =new HashMap();
// Add some elements to the HashMap
sites.put(1, "Google");
sites.put(2, "");
sites.put(3, "Taobao");
System.out.println("sites HashMap: "+ sites);
// Access all values in the HashMap
System.out.print("Values: ");
// values() returns a view of all values
// The for-each loop can access each value from the view
for(String value: sites.values()){
// Output each value
System.out.print(value +", ");
}
}
}
The output of the above program is:
sites HashMap: {1=Google, 2=, 3=Taobao}Values: Google, , Taobao,
