import java.util.ArrayList; import java.util.Arrays; class Demo { // One way static ArrayList<String> colors1 = new ArrayList<String>(Arrays.asList("red", "green", "blue")); // Another way static ArrayList<String> colors2 = new ArrayList<String>(Arrays.asList(new String[] {"red", "green", "blue"})); // But if its constants you can just use a regular array static final String colors3[] = { "red", "green", "blue" }; public static final void main(String args[]) { System.out.println("colors1=" + colors1); System.out.println("colors2=" + colors2); System.out.println("colors3=" + Arrays.toString(colors3)); } }

Output:

colors1=[red, green, blue] colors2=[red, green, blue] colors3=[red, green, blue]
