Java error! haven't seen solution elsewhere -
i writing program allow credit , debit of purchases 1 retailer , multiple buyers. after each buyer has purchased or made pmnt, need each transaction in monthly summary.
here have, error have @ point is:
main.java:136: error: not statement displayprocestran; ^ main.java:144: error: not statement displayprostrans; ^ this program:

problem
displayprocestran; is not statement. perhaps mean
displayprocestran(); side note on error messages
@ first, error messages might seem little cryptic, let's @ your's.
main.java:136: error: not statement displayprocestran; main.java:144: error: not statement displayprostrans; ^ well, it's telling found error ^ points to, @ end of displayprocestran. it's telling not statement. should tell you, have syntax error, means you've typed wrong. now, call methods stdin.readline() on place. should start try , make link why you're getting these errors.
other things i've noticed haven't seen mentioned
naming
well, guess big 1 how unreadable methods are. java naming conventions explain how methods , variables should laid out. example:
displayprocestran --- > displayprocestran (i think) encapsulation
you've got methods like:
void initrunbal() { runbal = begbal; } i'm not sure when user need use method. perhaps making it's access modifier private. ensuring interface presented users of classes, methods need. don't need know inner workings of class. that's called abstraction.
stuff won't compile
public void prostrans() throws ioexception; { transnum; } that isn't valid java. i'm not sure want that. perhaps want return transnum? in case, should be:
public int gettransnum() { return transnum; }
