this is the structure

{

public static void main (String arg[])
{
int [] dan = {150,250,350,450};
int greater = 0;
int index = 0;
int size = dan.length;
System.out.println("SEARCH ALGORITHM");
System.out.println("FIND THE GREATEST VALUE");
System.out.println(dan[0]);
greater = dan[0];
size = size -1 ;
while ( index < size );
{
index = index +1 ;
System.out.println(dan[index]);
if ( dan [index]> greater)
{
greater = dan [index];
}
}
System.out.println("The highest is: "+" "+greater);
}

}

Answer 1

Remove the Semi-Colon in while loop.. Your code will work fine..
while(index<size)
{....
...
...
}

Answer 2

If you want to achive max and min values
here's the simple way to do it
import java.util.Arrays;
public class Program
{
public static void main(String[] args) {
int arr[] = {12,50,2,60,7};
Arrays.sort(arr);
System.out.println("Min value "+arr[0]);
System.out.println("Max value "+arr[arr.length-1]);
}
}

Output
Min value 2
Max value 60

Description
The java.util.Arrays.sort(int[]) method sorts the specified array of ints into ascending numerical order.
