To create an array literal, you use braces, not square brackets. And you separate the array elements with commas, like - 

int[] numbers = {1,2,3,45};

Hi there! to add to what Manish said, you also have 2 equal signs in your array literal line:

  String[] teachers = new String = ["Jay";"Dave";"James"]; //old

  String[] teachers = {"name","name","name"}; //new form

You can get rid of the "new String" and the second = sign. (see second line)
