Any help.

public static void main(String args[])
    boolean p = true;
    int number;
    int j;
    Scanner s=new Scanner(System.in);
    while(p) {
        System.out.print("Enter a number");
        number = s.nextInt();
        if (number < 2)

I think the loop is supposed to terminate when the input is prime.

Testing for 1 seems needless.

It should really test for any number less than 2.

if (number < 2)
    continue;

bool prime ;
int number ;
do
{
    System.Console.Write("Enter a number");
    number = System.Int32.Parse( System.Console.ReadLine()) ; // get next value
    double sqrt = System.Math.Sqrt(number) ;
    prime = number > 1 ;
    for(int j = 2; prime && j <= sqrt; j++)
        prime = (number % j) != 0 ;
}
while(!prime) ;

myList.remove(0); 

somedatatype[] newArray = new somedatatype[oldArray.length-1];
System.arraycopy(oldArray,1,newArray,0,oldArray.length-1);
