Introduction
In this tutorial we will learn how to copy one array into another in this we
have array which is predefined by us
Let's see the logic
You firstly create or initialise a r a and then copy the all element into
another array called as B arrays . Where we use for loop for this we copy one
array element to other using this loop for more understanding you can see the
code below one by one copy one array to another by using the size of array.
After initialisation of array, we will display it on and after that we
perform for apply logic of for loop to copy a array into B and then give B
array as output.
Q) Java program to copy one array into another.
Sol
public class Main {
public static void main(String[] args) {
int A[]= new int [] {10, 20, 30, 40, 50};
int B[] = new int[A.length];
for (int i = 0; i < A.length; i++) {
B[i] = A[i];
}
System.out.println("Elements of array A: ");
for (int i = 0; i < A.length; i++) {
System.out.print(A[i] + " ");
}
System.out.println();
System.out.println("Elements of array B are following");
for (int i = 0; i < B.length; i++) {
System.out.print(B[i] + " ");
}
}
}
Output:
Elements of array A:
10 20 30 40 50
Elements of array B are following
10 20 30 40 50
