Two arrays are mostly used in programming – String array and Char array. Following program shows the initialization of a character array and also shows how to create an empty array.
Example on Char Array
public class CharArray
{
public static void main(String args[])
{
char vowels[] = {'a', 'e', 'i', 'o', 'u'}; // initializing char array
System.out.print("Vowels are: ");
for(char ch : vowels)
{
System.out.print(ch + ", ");
}
int x = vowels.length;
System.out.println("\n\nNumber of vowels: " + x);
char consonents[] = { }; // creating an empty array
System.out.println("Number of consonents: " + consonents.length);
}
}
