1.Basic Java example program get size of treeset
Output:
- package com.TreeSetExamplePrograms;
- public Class TreeSetGetSizeDemo{
- public static void main(String args[]) {
- //create TreeSet object
- TreeSet<String> treeSet = new TreeSet<String>();
- //add elements to TreeSet
- treeSet.add("I");
- treeSet.add("N");
- treeSet.add("S");
- treeSet.add("T");
- treeSet.add("A");
- treeSet.add("N");
- treeSet.add("C");
- treeSet.add("E");
- treeSet.add("O");
- treeSet.add("F");
- System.out.println(treeSet);
- System.out.println("Size of TreeSet : " + treeSet.size());
- //remove one element from TreeSet using remove method
- treeSet.remove("A");
- System.out.println("Size of TreeSet after removal of element A : " + treeSet.size());
- System.out.println(treeSet);
- }
- }
Output:
- [A, C, E, F, I, N, O, S, T]
- Size of TreeSet : 9
- Size of TreeSet after removal of element A : 8
- [C, E, F, I, N, O, S, T]
