Delete array

Di Java, array elemennya fix gan, gak bisa ditambah gak bisa dihapus. Kalo pengen yang dinamis, pakenya ArrayList.

Ya bisa, menggunakan teknik shifting untuk menyiasati fix lenght dari array itu sendiri.

<pre> import java.util.Scanner;

public class ElemRemoval {

public static void main(String[] args) {
    Scanner in = new Scanner(System.in);
    int[] intArr = {1, 2, 5, 12, 7, 3, 8};
    System.out.print("Enter Element to be deleted : ");
    int elem = in.nextInt();
    
    for(int i = 0; i < intArr.length; i++){
        if(intArr[i] == elem){
            // shifting elements
            for(int j = i; j < intArr.length - 1; j++){
                intArr[j] = intArr[j+1];
            }
            break;
        }
    }
  
    System.out.println("Elements -- " );
    for(int i = 0; i < intArr.length; i++){
        System.out.print(" " + intArr[i]);
    }                
}

} </pre>

hasilnya

<pre> Enter Element to be deleted : 5 Elements -- 1 2 12 7 3 8 8 </pre>

//java source code

import java.util.ArrayList;

public class tc {

public static void main(String...Naufal) {
    ArrayList<String> Animals = new ArrayList<String>();
    Animals.add("cat");
    Animals.add("fish");
    Animals.add("frog");
    System.out.println(Animals);
    Animals.remove("frog");
    System.out.println(Animals);
}

}

/* Output:

[cat, fish, frog] [cat, fish] */
