在java中将全名拆分为Salutation，Firstname和lastname

Question

I am receiving full name, i need to split this into Salutation, Firstname and lastname . for eg.

• Steve Emond==> Steve as Firstname , Emond as lastname(here Salutation is Empty)
• Mr Chris Barker ==> Mr as Salutation, Chris as Firstname , Barker as lastname
• Justin ==> Justin as lastname(Salutation and Firstname are empty)

Note: received Miss,Mr,Mrs as Salutation values.

Code:

 String FirstName="";
 String fullName="Barker";
String[] nameArray=fullName.split(" ");
if(nameArray.length<3)
{
    System.out.println("Salutation: " + nameArray[0]);
    System.out.println("LastName: " + nameArray[1]);
    System.out.println("FirstName: " + FirstName);
}else if(nameArray.length>=3){
    System.out.println("Salutation: " + nameArray[0]);
    System.out.println("LastName: " + nameArray[nameArray.length - 1]);
    for (int index = 1; index < nameArray.length - 1; index++) {
        FirstName = FirstName + " " + nameArray[index];
     }
    System.out.println("FirstName: " + FirstName.trim());
}

The above code works fine when all values given in input( ie Mr Chris Barker ), for the remaining case it failed. can anyone provide me the solution for this?

Method 1:

 String fullName="Steve Emond"; String[] nameArray=fullName.split(" "); if(nameArray.length==1) { System.out.println("LastName: " + nameArray[0]); }else if(nameArray.length==2){ System.out.println("FirstName: " + nameArray[0]); System.out.println("LastName: " + nameArray[1]); } else if(nameArray.length==3){ System.out.println("Salutation: " + nameArray[0]); System.out.println("FirstName: " + nameArray[1]); System.out.println("LastName: " + nameArray[2]); }

Using Regex Method 2:

 String fullName="Mr Justin raj Savarimuthu"; Pattern pattern = Pattern.compile(new String ("(Mr\\\\s|Miss\\\\s|Mrs\\\\s)")); if(fullName.matches("(Mr\\\\s|Miss\\\\s|Mrs\\\\s).*")) { System.out.println("Salutation:"+fullName.substring(0,fullName.indexOf(' '))); fullName=pattern.split(fullName)[1].trim(); } String[] parts = fullName.split(" "); String firstName=""; for(int i=0;i<parts.length-1;i++) { firstName=firstName+parts[i]+" "; } if(firstName!="") System.out.println("FirstName:"+firstName); System.out.println("LastName:"+parts[parts.length-1]);
