Answer:
Result is: 65
Explanation:
To analyze this code let us asign line numbers:
- public class Test {
- public static void main( String[] args )
- { int[] a; a = new int[ 10 ];
- for ( int i = 0; i < a.length; i++ )
- a[ i ] = i + 2;
- int result = 0;
- for ( int i = 0; i < a.length; i++ )
- result += a[ i ];
- System.out.printf( "Result is: %d\n", result );
- }
- }
On line 3, an array of ints is created of size 10
On line 4 and 5 a for loop is used to add values to the array. at the end of the execution of line 4 and 5, the array will contain the following elements: [2, 3, 4, 5, 6, 7, 8, 9, 10, 11]
On line 6 an int variable result is created and initialized to 0
line 7 and 8 allows a for loop through the array adding up all the elements of the array and assigning them to result
Line 9 outputs the value of result (Which is the total sum)
