I have two diffrent arrays one students name and one with there last names
String[] firstname = {"Joe", "bryan", "moe", "zoe"}; String[] Lastname = {"May", "Zoey", "Eden", "Pratt"}; I was wondering how i would go on getting an output like where it prints the students first name then right next it the students last name
e.g Joe May ,Bryan Zoey
I dont want to use print function to manually print each first and last name manually. I was wondering how i could print them all at once
If you are using Java stream you can use :
String[] fullName = IntStream.range(0, firstname.length) .mapToObj(i -> String.format("%s %s", firstname[i], lastname[i])) .toArray(String[]::new); I based in the fact the two arrays have the same size.
Outputs
[Joe May, bryan Zoey, moe Eden, zoe Pratt] In addition to an elegant answer by @YCF_L some more ways are given below:
public class Main { public static void main(String[] args) { String[] firstNames = { "Joe", "bryan", "moe", "zoe" }; String[] lastNames = { "May", "Zoey", "Eden", "Pratt" }; // First method StringBuilder sb = new StringBuilder(); for (int i = 0; i < firstNames.length && i < lastNames.length; i++) { sb.append(firstNames[i]).append(" ").append(lastNames[i]).append(", "); } sb.deleteCharAt(sb.length() - 2); // delete the last comma System.out.println(sb); // Second method String fullNames[] = new String[firstNames.length]; for (int i = 0; i < firstNames.length && i < lastNames.length; i++) { fullNames[i] = firstNames[i] + " " + lastNames[i]; } String fullNamesStr = String.join(", ", fullNames); System.out.println(fullNamesStr); } } Output:
Joe May, bryan Zoey, moe Eden, zoe Pratt Joe May, bryan Zoey, moe Eden, zoe Pratt 
in java 8 ,considering the condition that arrays has same size.
ArrayList<String> al=new ArrayList<>(); for(int i=0;i<firstname.length;i++) { al.add(fisrtname[i]+" "+lastname[i]); } //now u have a complete arraylist with you with all the full names in it
