Thread: Sorting parallel arrays

I want a method to sort the parallel arrays according to the ascending order of names.
The code is working however the names I enter is not sorted by ascending order. What am I doing wrong?

public class SecA {
 
    //Method to store names,ages and marks for 10 people into parallel arrays
    public static void recAray(String[] name,int [] age,double[] mark)
    {
        for(int i=0;i<name.length;i++)//For loop to prompt to enter 10 names,ages and marks based on the names length array
        {
            Scanner in=new Scanner(System.in);//Creating Scanner object "in" to get input form the keyboard in the recAray method 
              System.out.println("Enter name");//Prompting to enter name
                name[i]=in.nextLine();
                    System.out.println("Enter age");//Prompting to enter age
                        age[i]=in.nextInt();
                            System.out.println("Enter mark");//Prompting to enter age
                                mark[i]=in.nextDouble();
 
             //Displaying names, ages and marks in array element [i]              
            System.out.println("Person is:"+" "+name[i]+" "+"Age is:"+" "+age[i]+" "+" "+"Mark is:"+
                                " "+mark[i]);
        }
    }
 
 
 
    //Method to sort the parallel arrays according to the ascending order of names.        
    public void sortD (String[] name, int[] age, double[] mark) 
    {
        for (int i = 0; i < age.length - 1; i++) 
        {
            for (int j = 0; j < age.length -1-i; j++) 
            {
                if (age[j] > age[j + 1]) 
                {
        /*
        *Swap age with lowest age
        */
                int ageTemp = age[j];
                        age[j] = age[j + 1];
                               age[j + 1] = ageTemp;
 
                        /*
                         *   Swap name using the same index
                         *   of the age
                        */
                        String nameTemp = name[j];
                                name[j] = name[j + 1];
                                    name[j + 1] = nameTemp;
 
                                  /*
                                   *   Swap marks using the same index
                                   *   of the age
                                   */
                                       double markTemp=mark[j];
                                                mark[j]= mark[j + 1];
                                                    mark[j + 1]=markTemp;
                }
 
           }
      }

Yes,,thats what I'm doing. How do i swap the names. I don't know how to compare them as they are Strings.
