i know there quite few errors in code, can't find them/don't understand them. doing wrong?

update: thank help. have managed clear out errors except one. still errors on getgradescore.

error: cannot find symbol

any appreciated! i've spent hours on , can't figure out. i'm confused classes , methods.

if try compile code you'll ton of syntax errors. here 3 of major offenders found , proposed solutions

1) quizscore1, quizscore2, , quizscore3 undeclared. do, however, have quizscore variable. if want store 3 quizscores, can either make list of scores, or can declare them. suggest arraylist. you'll need add more functions, 1 each score.

2) public boolean equals (otherquizscore) not allowed. type of otherquizscore? add type.

3) multiple return statements. return statement end function. if have 3 return statements in row, second 2 never run.

there slew of errors in code. if put ide (i suggest eclipse if don't have it) you'll see each error marked red underline, corresponding error message.
