Getting Largest Int From an Array of Integers

Question

public class TestMe
    public TestMe(int ai[])
        _numbers = ai;
public int getBiggest1()
        int i = _numbers[0];
        for(int j = 1; j < _numbers.length; j++)
            if(_numbers[j] >= _numbers[j - 1] && i < _numbers[j])
                i = _numbers[j];
        return i;
    public int getBiggest2()
        double d = Math.random();
        int i = _numbers[0];
        for(int j = 1; j < _numbers.length; j++)
            if(d >= 0.10000000000000001D && i < _numbers[j])
                i = _numbers[j];
        return i;
  private TestMe()
    private int _numbers[];
}can anyone see what is wrong with either of the two methods as regards returning the largest integer from an array of integers.
As far as I can see they work no matter what ints are in the array.
Any ideas anyone ?

Answer 1

I used the following client program to use ur class:
I also modified ur class a bit and made the other constructor (the one with no arguments) as public to extend the class.
Both the functions, viz, getBiggest1() and getBiggest2() are working fine...
Now, I am new to JAVA so I might have made mistakes. Please correct me if there is anything wrong.
/*Here is ur class that i have modified*/
public class GetBiggest {
     public GetBiggest(int ai[])     {
          _numbers = ai;   
     public int getBiggest1()     {
          int i = _numbers[0];
          for(int j = 1; j < _numbers.length; j++)           
          if(_numbers[j] >= _numbers[j - 1] && i < _numbers[j])
               i = _numbers[j];
          return i;
     public int getBiggest2() {       
          double d = Math.random();
          int i = _numbers[0];       
          for(int j = 1; j < _numbers.length; j++)           
          if(d >= 0.10000000000000001D && i < _numbers[j])
               i = _numbers[j];
          return i;
public GetBiggest()     {
private int _numbers[];
/*Ur class ends here*/
/*My client program starts here*/
import java.lang.*;
public class TestBiggest extends GetBiggest
     public static void main (String args[])
          int[] arrNums = {30, 20, 40, 10};
          GetBiggest GB = new GetBiggest(arrNums);
          int greatest = 0;
          try
               greatest = GB.getBiggest2();
               System.out.println("\nBiggest number is : " + greatest);
          }//end try block
          catch(Exception e)
               System.out.println("Some error");
          }//end catch block
     }//end main
}//end class
/*End of my client program*/
