Java Vector removeRange() Method

The removeRange() method of Java Vector class is used to delete all elements from the vector whose index is between fromIndex, inclusive and toIndex, exclusive. The removal of elements shifts any succeeding elements to the left (reduces their index).

Syntax

Following is the declaration of removeRange() method:

Parameter

DataType	Parameter	Description	Required/Optional
int	fromIndex	It is an index of the first element which will be removed.	Required
int	toIndex	It is an index after the last element which will be removed.	Required

Return

This method does not return anything. It only removed the specified range of an element from the vector.

Exceptions

IndexOutOfBoundsException– This method has thrown an exception if the index of an array is out of range i.e. (index < 0 || index >= size()).

Compatibility Version

Java 1.2 and above

Example 1

  import java.util.*;  public class VectorRemoveRangeExample1 extends Vector {    public static void main(String arg[]) {      //Create object for vector class       VectorRemoveRangeExample1 vec = new VectorRemoveRangeExample1();      //Add elements in the vector      vec.add(9);      vec.add(8);      vec.add(7);      vec.add(6);      vec.add(5);      //Displaying the vector element before removal      System.out.println(“Vector element before removal: ” +vec);      //Remove the range of an element      vec.removeRange(1,3);           //Displaying the vector element after removal      System.out.println(“Vector element after removal: ” +vec);      }              }  

Test it Now

Output:

Vector element before removal: [9, 8, 7, 6, 5]  Vector element after removal: [9, 6, 5]

Example 2

  import java.util.*;  public class VectorRemoveRangeExample2 extends Vector {    public static void main(String arg[]) {  //Create object for vector class  VectorRemoveRangeExample2 vec=new VectorRemoveRangeExample2();  //Add an elements in vector  vec.add(“w”);  vec.add(“e”);  vec.add(“l”);  vec.add(“l”);  vec.add(“d”);  vec.add(“c”);  vec.add(“o”);  vec.add(“m”);  vec.add(“e”);              //Displaying the vector element before removal  System.out.println(“Vector elements: “+vec);  //Remove elements from between given index range values  vec.removeRange(3,5);              //Displaying the vector element after removal  System.out.println(“Vector elements after removal: “+vec);        }              }  

Test it Now

Output:

Vector elements: [w, e, l, l, d, c, o, m, e]  Vector elements after removal: [w, e, l, c, o, m, e]
