question:

//Given an array and a value, remove all instances of that > value in place and return the new length.
//
//The order of elements can be changed. It doesn't matter what you leave beyond the new length.

answer:

public class removeElement {
    public static int removeElement(int array[],int elem){
        int i = 0;
        int j = 0;
        for (i =0;i<array.length;i++){
            if (array[i]== elem){
                continue;
            }
            array[j] =array[i];
            j++;
        }
        return j;
    }
    
    public static void main(String[] args){
        int[] array1 = {1,2,2,3,2,4};
        int length = removeElement(array1,2);
        for (int i=0;i<length;i++){
            System.out.println(array1[i]);
        }
    System.out.println("array length is "+ length);
    }
