java character to ascii 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: 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.

Example 3: how to get ascii value of string letter in java

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

Example 4: how to add a number to the ascii value of a char in java

char a = 97+1;
char b = 'a'+2;
r = (char)(1+5)
