Answer:
The C language code is a class called Test that accepts an array, duplicates it, reinitializes the first array to the first two items of the previous array, and loops through the array to print both items.
Explanation:
public class Test{
public static void main(String args[]){
int[] x={1,2,3,4}; //here declare array x with 1 2 3 4
int[] y=x; //here copy the x array into y array
x=new int[2]; //here reintilized the array size which is 2
for(int i=0;i<.length;i++){ //here now array length is 2 it iterates 2 times
System.out.print(x[i]+" ");
}
}
