There's lots of ways to do this. I've gone for one that's hopefully pretty easy to follow as it sounds like you're just getting started. Drop the forum a line of there's anything you don't understand.
Code:
public class string_split {
public static void main(String argv[]) {
// original string
String original = "ABCDEFGHIJKL MNOP QRSTUV XYZ AC DEFGHI JKLMNO PQRSTU VXY AJHKDJSHJSHDKSJ DSJKDNSNDJSNUDNWINWU NIWDWNWSOMWSMWMXKMXMS LXMSKMXKLSMJFNDCDJKBC HDBDHBJCBDJBCHDB CBHDBCJBHSKDS CB DJCHDKBDJCB CCHDBCJH DHBDCHBSJCBDKS";
// strip out spaces, replace them with null character
String noSpaces = original.replace(' ', '\0');
String[] groupsOfFive = new String[100]; //change for big values
// loop through string feeding 5 character substrings
// into an array
int j=0;
int i;
for (i=0;i<noSpaces.length()-5;i += 5) {
groupsOfFive[j] = noSpaces.substring(i,i+5);
j++;
}
// Print what we got. Linebreak every ten blocks
for(i=0;i<j;i++) {
if (i%10==0)
System.out.println();
System.out.print(groupsOfFive[i] + " ");
}
}
}
The output is:
