Thread: Program of an Array in Java

Hello eric and welcome to the Java Programming Forums.

You can use this code below. I have used the Scanner class to take user input from the console.
This will then set the size of the array depending on what int value the user enters:

import java.util.Scanner;
 
public class Eric {
 
    public static void main(String[] args) {
 
          System.out.println("Enter Array size: ");
          Scanner sc = new Scanner(System.in);
 
          int arraySize = sc.nextInt();
 
          String[] myArray = new String[arraySize];
 
    }
 
}

To take this one step further, ive added this code so the user can now populate each array field and once its filled it will print its results:

import java.util.Scanner;
 
public class Eric {
 
    public static void main(String[] args) {
 
          System.out.println("Enter Array size: ");
          Scanner sc = new Scanner(System.in);
 
          int arraySize = sc.nextInt();
 
          String[] myArray = new String[arraySize];
 
          System.out.println("Array size set to " + arraySize);
 
          //Populate the array
          for(int a = 0; a < myArray.length; a++){
              System.out.println("Enter Array value [" + a + "]:");
              myArray[a] = sc.next();
          }
 
          //Print array values. Can also add Array sort code here.
          for(int b = 0; b < myArray.length; b++){
              System.out.println(myArray[b]);
          }
 
    }
 
}

To sort the Array you could use the java.util.Arrays class:
