Multiple constructor help needed

Question

Good day to all.
I have an object that has 2 constructors. I want the first constructor to be able to call the second. Is this possible?
Pseudo example.....
public class O{
  int val;
  public O(String S) throws Exception{
    int i = Integer.parseInt(S);
    new O(i);
  public O(int v){
    this.val = v;
}Thanks

Something like:
public class O{
  int val;
   public O(String S){
   try{
     this(Integer.parseInt(S));
   }catch(NumberFormatException e){
    System.out.println("Unconvertable String")
   public O(int v){
     this.val = v;
