Java Programming which act the same as function "goto(x,y) " in C Programming!!!

does the program run correctly????Code:public static final SIZE 72;
if i create a random access file without ristriction,whi le using the program and updating a record( for example add some information to the record)doesn't it distibute the date of th next record?

well, i'v read some where that for creating a random access file we should spesify an exact size for every record which we want to keep.
for example if we want to create a file which can take 100 record and every record will occure 32 byte (at maximom size),we should give this size(32 byte) to the program.it means after finishing the program we can't have a record with size of 42 byte.
now my question is : is it any way that we can...Leave a comment:

please let me tell you what i understand from this way:
we know that to convert every character to an integer we have to subtract 48 from that character and because charachter 0 is equal to -48 you do that to convert a & b into integers!!!!
thank you very much
iwill write code of this program right away and send this to know your what you think about that...:)Leave a comment:

let me describe from the begining as my professor want:
i have to get two array of 40-digit number(num1 & num2),then convert these two into strings of 40-digit number( array---->string) and then do add and subtract on these two strings.
( NOTE: what not to do : i shouldn't convert every digit(character in strings) into integer and i have do some kind of character add or character subtract on them).
and i have no sugesstion...Leave a comment:

well i thought i can add each digit(character ) of the string1 and string2 with eachother and put it in the same position of the third string as shown below:
and ofcourse have some rule too do this correctly in the program...and do the same thing for subtract...Code:int[] a1=new int[40]; int[] a2=new int[40]; int[] a3=new int[40]; ..... a3[0]=a1[0]+a2[0];
but my professor didn't accept...Leave a comment:
