Remove method of array

Question

Implement the following method in the class Project 11 to return a new array that contains all the elements of the array a not in b.
Public static int [] remove (int[] a, int[] b)
For example, if the array a is {5,3,2,7,1} and the array b is {8,2,5} the remove method should return the array {3,7,1}.
Im having trouble getting it run correctly, and i think my problem is with the remove method that i made
//heres my code
public static void main(String[]args) {
int [] first = {2,5,4,1,9};
int [] second = {5,10,8,1};
int duplicate =0;
for (int i = 0; i < first.length; i++) {
               for (int j =0; j < second.length; j++){
                    if (first[i] == second[j])
                         duplicate++;
                    remove(first, second);
System.out.println(first);
public static int [] remove(int[] a, int []b){
for(int i = 0; i < a.length; i++) {
if(a[i] == b) {
int[] c = new int[a.length - 1];
return c;
return a;

Answer 1

im having trouble with the remove method. im suppose to return a new array that contains all the elements of the array a not in b.
Public static int [] remove (int[] a, int[] b)
For example, if the array a is {5,3,2,7,1} and the array b is {8,2,5} the remove method should return the array {3,7,1}.
//heres my code
public static void main(String[]args) {
int [] first = {2,5,4,1,9};
int [] second = {5,10,8,1};
int duplicate =0;
for (int i = 0; i < first.length; i++) {
for (int j =0; j < second.length; j++){
if (first == second[j])
duplicate++;
remove(first, second);
System.out.println(first);
public static int [] remove(int[] a, int []b){
for(int i = 0; i < a.length; i++) {
if(a[i] == b) {
int[] c = new int[a.length - 1];
return c;
return a;
