how do i go back in question number 1 in this java code?..

Use a switch statement on a variable representing the question you are at. Then, to return to a specific question, you can reset the variable to that question, putting all of this in a loop.

Enclose the code you want to repeat in a loop like a while() loop.

  while(someCondition) {
     <  current code here >
  }  // end while()

To exit the loop: Change someCondition to false or use the break statement.
