Consider the program below: 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 ); } // end main } // end class Test The output of this program will be:

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)
