Question

I can’t get my head around this at the moment so any help would be great..

for(EdgeOf e: gra.getEachVertex()) {
     System.out.println(e.getId());
}

From this I get a result of 41_1, 32_2 but I want to split these values up and reuse them. I can’t seem to pull these values without getting the them both together..?

How can i string.split this?

Answer 1

At 1st iteration e.getId() returns 41_1, so u can split it as 41 and 1 by using split(“_”), do the same in 2nd iteration also..

for(EdgeOf e: gra.getEachVertex()) {
String str = e.getId();
String[] str2 = str.split("_");
     System.out.println(str2[0] + " " + str2[1]);
}
