AbstractMap.SimpleEntry<K, V> is used to maintain a key and a value entry. The value can be changed using the setValue method. This class facilitates the process of building custom map implementations.
getValue() method of AbstractMap.SimpleEntry<K, V> returns the value corresponding to a entry made in this class.
Syntax:
public K getValue()
Parameters: This method accepts nothing.
Return value: This method returns the value corresponding to this entry.
Below programs illustrate getValue() method:
Program 1:
// Java program to demonstrate// AbstractMap.SimpleEntry.getValue() method  import java.util.*;import java.util.AbstractMap.SimpleEntry;  public class GFG {      @SuppressWarnings({ "unchecked", "rawtypes" })    public static void main(String[] args)    {          // create a ArrayList of Map        ArrayList<AbstractMap.SimpleEntry<Integer, Integer> > arrayList = new ArrayList<AbstractMap.SimpleEntry<Integer, Integer> >();          // add values        arrayList.add(new AbstractMap.SimpleEntry(0, 123));        arrayList.add(new AbstractMap.SimpleEntry(1, 130));        arrayList.add(new AbstractMap.SimpleEntry(2, 994));          // print keys        for (int i = 0; i < arrayList.size(); i++) {              // get map from list            AbstractMap.SimpleEntry<Integer, Integer> map = arrayList.get(i);              // get value from map using getValue()            int value = map.getValue();              System.out.println("Value " + value);        }    }} |
Output:
Value 123 Value 130 Value 994
Program 2:
// Java program to demonstrate// AbstractMap.SimpleEntry.getValue() method  import java.util.*;  public class GFG {      @SuppressWarnings({ "unchecked", "rawtypes" })    public static void main(String[] args)    {          // create a ArrayList of Map        ArrayList<AbstractMap.SimpleEntry<String, String> > arrayList = new ArrayList<AbstractMap.SimpleEntry<String, String> >();          // add values        arrayList.add(new AbstractMap.SimpleEntry(" 001AB ", " Emp 1"));        arrayList.add(new AbstractMap.SimpleEntry(" 011AC ", " Emp 2"));        arrayList.add(new AbstractMap.SimpleEntry(" 111AD ", " Emp 3"));        arrayList.add(new AbstractMap.SimpleEntry(" 101BE ", " Emp 4"));        arrayList.add(new AbstractMap.SimpleEntry(" 110CE ", " Emp 5"));          // print keys        for (int i = 0; i < arrayList.size(); i++) {              // get map from list            AbstractMap.SimpleEntry<String, String> map = arrayList.get(i);              // get value from map using getValue()            String value = map.getValue();              System.out.println("Value " + value);        }    }} |
Output:
Value Emp 1 Value Emp 2 Value Emp 3 Value Emp 4 Value Emp 5
