Java Examples - Array Expansion
Java ExamplesThe following example demonstrates how to expand an array after it has been initialized:
Main.java file
public class Main {
public static void main(String[] args) {
String[] names = new String[] { "A", "B", "C" };
String[] extended = new String[5];
extended[3] = "D";
extended[4] = "E";
System.arraycopy(names, 0, extended, 0, names.length);
for (String str : extended){
System.out.println(str);
}
}
}
The output of running the above code is:
A B C D EOther Extensions
