How to check ASCII value in Java?
In Java, you can check the ASCII value of a character by simply casting the character to an integer. The ASCII values range from 0 to 127, and each character is assigned a unique value. You can use the following code snippet to check the ASCII value of a character:
“`java
char ch = ‘A’;
int asciiValue = (int) ch;
System.out.println(“ASCII value of ” + ch + ” is ” + asciiValue);
“`
This will output: ASCII value of A is 65
By casting the character to an integer, you can easily find out the ASCII value of any character in Java.
