How to make "pair" of more than 2 elements then sort by first element in java?

Question

Paring in java

Answer 1

Hello R_C

Can you add an example?

If you have only a pair and if you are using numbers you can use < and >.

for example 4, 3

4 > 3 -> swap them to get 3, 4

Answer 2

Can you please make your question more descriptive? Also, try to include a program of your own, as currently this seems like homework.

Answer 3

Hello R_C

My idea is to store the name and the index in a hashmap.

a has index 0, 4 belongs to a and has index 0 and 25000 belongs to a and has index 0.

a = 0
c = 1
g = 2

After storing the index you can do what ever you want with the names. And you don't need to do anything with the other arrays.

Here is a small code example:

What if two or more names are same

Answer 6

Denise Roßberg
if there are three arrays
Name={"a", "c", "g"}
ID={4,1,9}
Salary={25000,42000,11000}
i.e; a person name "a" having ID 4 and salary 25000
I want to sort the combined array i ascending according to ID. i.e;
Name ={"c", "a", "g"}
ID = {1,4,9}
Salary = {42000,25000,11000}
and show the answer as
c 1 42000
a 4 25000
g 9 11000
