Delete All Elements From ArrayList In Java

Chapter: Data Structures Last Updated: 11-08-2017 09:27:53 UTC

Program:

            /* ............... START ............... */
                
import java.util.ArrayList;

public class JavaArrayListDelete {
	public static void main(String a[]){
        ArrayList<String> arryList = new ArrayList<String>();
        //adding elements to the end
        arryList.add("Java");
        arryList.add("Scan");

        System.out.println("Actual ArrayList:"+arryList);
        arryList.clear();
        System.out.println("After clear ArrayList:"+arryList);
    }
}
                /* ............... END ............... */
        

Output

Actual ArrayList:[Java, Scan]
After clear ArrayList:[]

Notes:

  • java.util.ArrayList.clear() method removes all of the elements from this list.The list will be empty after this call returns.
  • Syntax : public void clear().
  • When performing ArrayList.clear() you only remove references to array elements and sets size to 0, however, capacity stays as it was.
