Change the score.
Delete the score and student's name. "
Check the score by student name. "
Check all student scores. "
*6. The average score of all students is counted. "
*7. Return to the previous level. "

Two. The main problems that arise are:

1. Strings are to be used in equals, for example:

String a = "a";

String B = "B";

if (A.equals (B)) {

System.out.println ("more successful. ");

}

2.equals cannot compare null, an error occurs.

3. For each module, a while loop is added. It feels better to use flag, and it's not easy to get it wrong. The overall format structure is also more normative.
