To iterate through hashtable in java, first we have to get all keys as set object and then fetch each element using key.
Example:
package com.w3spoint;
import java.util.Hashtable;
import java.util.Set;
public class Test {
public static void main(String args[]){
//Create Hashtable object.
Hashtable<String, String> hashtable = new Hashtable<String, String>();
//Add objects to the Hashtable.
hashtable.put("1", "Jai");
hashtable.put("2", "Mahesh");
hashtable.put("3","Vivek");
System.out.println(hashtable);
Set<String> keys = hashtable.keySet();
for(String key: keys){
System.out.println("Value of "+key+" is: "+hashtable.get(key));
}
}
} |
package com.w3spoint;
import java.util.Hashtable;
import java.util.Set;
public class Test {
public static void main(String args[]){
//Create Hashtable object.
Hashtable<String, String> hashtable = new Hashtable<String, String>();
//Add objects to the Hashtable.
hashtable.put("1", "Jai");
hashtable.put("2", "Mahesh");
hashtable.put("3","Vivek");
System.out.println(hashtable);
Set<String> keys = hashtable.keySet();
for(String key: keys){
System.out.println("Value of "+key+" is: "+hashtable.get(key));
}
}
}
Output
{3=Vivek, 2=Mahesh, 1=Jai}
Value of 3 is: Vivek
Value of 2 is: Mahesh
Value of 1 is: Jai |
{3=Vivek, 2=Mahesh, 1=Jai}
Value of 3 is: Vivek
Value of 2 is: Mahesh
Value of 1 is: Jai
