char ascii value java code example

Example 1: how to convert an ascii number to character in java

// From Char to Ascii
char character = 'a';    
int ascii = (int) character;

// From Ascii to Char
int ascii = 65;
char character = (char) ascii;

Example 2: ascii values to display certain characters in java

/*ASCII acronym for American Standard Code for Information Interchange.
It is a 7-bit character set contains 128 (0 to 127) characters.
It represents the numerical value of a character.
For example, the ASCII value of A is 65.*/
char a = 65, b = 66, c = 67;
System.out.println(a);
System.out.println(b);
System.out.println(c);

/* this is how you type ASCII values in java */

Example 3: how to get a character in java in ascii

// Very simple. Just cast your char as an int.

char character = 'a';    
int ascii = (int) character;

//In your case, you need to get the specific Character from the String first and then cast it.

char character = name.charAt(0); // This gives the character 'a'
int ascii = (int) character; // ascii is now 97.

//Though cast is not required explicitly, but its improves readability.

int ascii = character; // Even this will do the trick.
