Starting with the Count.j example, implement Butcher's Easter Algorithm to calculate and print the date of Easter for the next 10 years in JVM assembly language.

I keep getting errors on line 67, 68, 70. I dont understand why!!! any help much appreciated

my code so far

.class public Easter .super java/lang/Object

; ; standard initializer .method public ()V aload_0 invokenonvirtual java/lang/Object/()V return .end method

.method public static main([Ljava/lang/String;)V ; set limits used by this method .limit locals 20 .limit stack 6

; setup local variables:

; 1 - the PrintStream object held in java.lang.System.out getstatic java/lang/System/out Ljava/io/PrintStream; astore_1

; 2 - the integer 10 - the counter used in the loop bipush 10 sipush 2017 istore_2 ;count is in 2 istore 4 ;year is in 4

; now loop 10 times printing out a number

Loop:
