How to convert character to ASCII number in java?

ASCII stands for American Standard Code for Information Interchange. Each and every character has it ASCII equivalent number.We can use following way to find ascii equivalent of character.

class AsciiConvert{
public static void main(String arg[]){
char ch='N';
System.out.println((int)ch);
}
}

Output after execution : 78 If we wanted to convert string to ASCII values first we need to convert string into char array then again we apply the method we used above.

class AsciiConvert{
public static void main(String arg[]){
StringBuffer sb = new StringBuffer();
 char[] letters = "test".toCharArray(); 
for (char ch : letters) {
 sb.append((byte) ch); 
} 
System.out.println(sb.toString());
}
