Question

I NEED A BASIC JAVA PROGRAM USING ARRAY TO FIND THE AVERAGE FOR 10 STUDENTS. THEN THERE SHOULD BE A COUNTER FOR STUDENTS AND AN ACCUMULATOR FOR THE AVERAGE AND INPUT VALIDATION FOR THE THREE TEST SCORES; THEY MUST BE BETWEEN 0 TO 100. ALSO THE AVERAGE AND AVERAGE ACCUMULATOR SHOULD BE FORMATTED TO TWO DECIMAL PLACES AND AT THE END ALL 10 STUDENTS SHOULD BE IN A KIND OF A TABLE SHOWING FIRST NAME, MIDDLE INITIAL, LAST NAME TEST 1 TEST 2 TEST 3 AND AVERAGE...…. THANKS IN ADVANCE
