So I am trying to create a ArrayList of Integers and then iterate variables into it. Only the first value that I specify is being added.
private ArrayList<Integer> heights(String detail) {
ArrayList<Integer> heights = new ArrayList<Integer>();
heights.add(0);
switch(detail) {
case "L": for(Integer i = 100; i <= 1000; i=+50) { heights.add(i); } break;
case "H": for(Integer i = 100; i <= 1000; i=+25) { heights.add(i); } break;
}
return heights;
}
Value of heights("H"):
heights: [0]
The Problem is in for loop. Use int
instead of Integer
class....
The code below works properly...
import java.util.*;
class Test{
private ArrayList<Integer> heights(String detail) {
ArrayList<Integer> heights = new ArrayList<Integer>();
heights.add(0);
switch(detail) {
case "L": for(int i = 100; i <= 1000; i=i+50) { heights.add(i); } break;
case "H": for(int i = 100; i <= 1000; i=i+25) { heights.add(i); } break;
}
return heights;
}
public static void main(String args[]){
Test t = new Test();
System.out.println(t.heights("H"));
}
}
