Hello Programmers,
is it possible to create new 1D array from 2D array?
for example from this array
String[][] ArrVal= {
{"rec", "02"},
{"proc", "03"},
{"hscode", "10"},
{"sitc", "21"}};
take first column of ArrVal[0] and make this as new array with ArrVal[1] as value of new array, for example :
String[] rec = {"02"}
String[] proc = {"03"}
String[] hscode = {"10"}
String[] sitc = {"21"}
is it possible to create new 1D array from 2D array?
yes
How to create new array from array 2D member?
iterate over the 2d array and save the desired values from the 2d array to the new array
That sounds like a HashMap, where you have lots of entries, each entry combines a key (eg "rec") and a value (eg "02"). You can use the keys to access the values.
This tutorial is a bit out of date, but it illustrates the basic ideas: http://www.javadeveloper.co.in/java-example/java-hashmap-example.html
