Random r = new Random( );
for( int i = 0; i < GAMES; i++)
for( int j = 0; j < NUMBERS_PER_GAME; j++ )
numbers[ r.randomInt( 1, DIFF_NUMBERS ) ]++;
// Output the summary
for( int k = 1; k <= DIFF_NUMBERS; k++ )
System.out.println( k + ": " + numbers[ k ] );
}

Answer 1

I changed to import java.util.Random
and I get one Error Message:
Lottery.java:23: cannot resolve symbol
symbol : method randomInt (int,int)
location: class java.util.Random
numbers[ r.randomInt( 1, DIFF_NUMBERS ) ]++;
