1. Assume that v is a Vector. What does the following program part do? (2 points)
int i = v. size() - 1;
while( i >= 0 ) {
System. out. println( v. get( i ) );
i--;
}
It prints out all the elements of v in inverse order.
2. Write a program part that does the same thing as the one above, but uses an array instead of a Vector.
(2 points)
int i = a. length – 1;
while( i >= 0 ) {
System. out. println( a[ i ] );
i--;
}
3. What does the following program part print out?(1 point)
int[] a = new int[ 4 ] ;
a[ 3 ] = 34;
a[ 2 ] = 12;
a[ 1 ] = 45;
a[ 0 ] = 11;
for( int i: a ) {
System. out. println( i );
}
11
45
12
34
