initialize multidimensional list in java
import java.util.Arrays.*; List<List<T>> items = new ArrayList<>(Arrays.asList( Arrays.asList(T ...items), Arrays.asList(T ...items1), Arrays.asList(T ...items2) )); //for string type : List<List<String>> items = new ArrayList<>(Arrays.asList( Arrays.asList("a", "b", "c"), Arrays.asList("d", "e", "f"), Arrays.asList("g", "h", "i") )); System.out.println("Output : " + items.toString()); //Output : [ [a, b, c], [d, e, f], [g, h, i] ] //Another answer from stackoverflow suggests a way without using built-in as:List method // Link : https://stackoverflow.com/a/6233024
