Copying an array to another
In this tutorial, you will learn how to copy data from one array to another.

Copying an array to another

Java Copy Array Example:
In this tutorial, you will learn how to copy data from one array to another. Here, providing you an example with code and its explanation to given below.

This is a program that follows one dimensional array. In this program, firstly we have to define a class "CopyArray". Now, we take two integer type array like: array1[] and array2[]. The array1[] contains some integer type values (2,3,4,5,8,9) and another is blank. After initializing this, now we get number of rows and columns by using the array1.length. We use the 'for' loop statement for displaying and copying ( array1[j] = array2[j] ) the array.

Here is the code of this program:


public class CopyArray {

  public static void main(String[] args) {

    int array1[]= {2,3,4,5,8,9};

      int array2[] = new int[6];

        System.out.println("array:"); 

    System.out.print("[");

        for (int i=0; i<array1.length; i++){

      System.out.print(" "+array1[i]);

    }

    System.out.print("]");

    System.out.println("\narray1:");

    System.out.print("[");

    for(int j=0; j<array1.length; j++){

      array2[j] = array1[j];

      System.out.print(" "+ array2[j]);

    }

    System.out.print("]");

  }

}
