Sorting a time intervals

Question

I am giving a time interval in the form of two arrays.

A[0]=  2  B[0]=3
A[1]=  9  B[1]=11
A[2] = 5 B[2]=6
A[3] = 3 B[3]=10

I want to sort the i

Answer 1

Step 1: Java is an object oriented language; learn to use objects.

Possible class for the time interval

public class TimeInterval implements Comparable
{
    private int end;
    private int start;

    public TimeInterval(
        final int end,
        final int start)
    {
        this.end = end;
        this.start = start;
    }

    public int getEnd()
    {
        return end;
    }

    public int getStart()
    {
        return start;
    }

    public int comareTo(final TimeInterval other)
    {
        if (other == null)
        {
            return -1; // this will put the null value objects at the end.
        }

        return start - other.start;
    }
}
