What must the test be so that the following fragment prints out the integers 5 through and including 15? for ( int j = 5; ________ ; j++ ) { System.out.print( j + " " ); } System.out.println( );

j<16

What must the test be so that the following fragment prints out the integers 5 through and including 16? for ( int j = 5; ________ ; j++ ) { System.out.print( j + " " ); } System.out.println( );

j<=16

for ( int j = 0; j < 5; j++ ) { System.out.print( " j " ); } System.out.println( ); What does the code output

j j j j j

var i = 0; while (i < 3) { println("hi"); println("bye"); i++; }

hi bye hi bye hi bye

var i = 0; while (i < 3) { println("hi"); i++; }

hi hi hi

var i = 0; while (i < 3) { println("hi"); i++; } println("bye");

hi hi hi bye

var i = 0; while (i <= 3) { println("hi"); i++; }

hi hi hi hi

var i = 0; while (i < 0) { println("hi"); } What does the code output?

It won't output anything.
