<p>Our school uses BlueJ</p>
<p>If you’re just beginning with Java, here’s a starting point: [Beginning</a> Java](<a href=“http://mathbits.com/MathBits/Java/JavaOpenPage.htm]Beginning”>Beginning Java)</p>
<p>If you’re a little more advanced try here: [Introduction</a> to Computer Science using Java](<a href=“http://programmedlessons.org/java5/index.html]Introduction”>Introduction to Computer Science using Java) as well</p>
<p>You might want to take a look at the Grid World case study ( [AP</a> Central - GridWorld Case Study](<a href=“Supporting Students from Day One to Exam Day – AP Central | College Board”>AP Computer Science A Classroom Resources – AP Central | College Board) ) </p>
<p>Good luck!</p>
