Answer:
The complete program is given below.
The complete program is given below.
Notice that the two for statements are the same.
This is very common.
It would be nice to copy this program to a file and to run it.
When you do this,
change the length of the array (the 5) to some other value (say, 9) and note the effect.
Review: Recall that the scope of the identifier index
declared in the for statement is limited to just the body of its loop.
So in the program, there are two variables, each named index, and each
limited in scope to the body of its own for.
import java.util.Scanner ;
class InputArray
{
public static void main ( String[] args )
{
int[] array = new int[5];
int data;
Scanner scan = new Scanner( System.in );
// input the data
for ( int index=0; index < array.length; index++ )
{
System.out.println( "enter an integer: " );
data = scan.nextInt();
array[ index ] = data ;
}
// write out the data
for ( int index=0; index < array.length; index++ )
{
System.out.println( "array[ " + index + " ] = " + array[ index ] );
}
}
}
The variable data is not really needed in this program.
Mentally change the program so that this variable is not used.
