Array -- Concatenate two arrays
Write a return method that can concatenate two arrays
Solution:
public static int[] concatTwoArrays(int[] arr1 , int[] arr2) {
int[] result = new int[arr1.length + arr2.length];
int i = 0;
for(int each: arr1) {
result[i] = each;
i++;
}
for(int each: arr2) {
result[i] =each;
i++;
}
return result;
}concat two arrays
public static void main(String[] args) {
String[] arr3 = {"A", "B", "C","Z","N"};
String[] arr4 = {"D", "E", "F","G","U"};
ArrayList<String> list1 = new ArrayList<>();
// [A, B, C, Z, N, D, E, F, G, U]
for( String each: arr3 ){
list1.add( each );
}
for(String each1 : arr4 ){
list1.add(each1);
}
System.out.println(list1); // [A, B, C, Z, N, D, E, F, G, U]Copyright © 2021 Codeinu
