You can directly write this code:-

for(char i=0; i<=127; i++) {

System.out.println((int)i+" = "+i);
}

Thanks Sir for this tutorial. By using println I've written the below code pls have a look.

public class AsciiDemo {

public static void main(String[] args) {
for (int i=0; i<128;i++){

System.out.println(i+ ":" +(char)i);
}}

How did the compiler get to know that there should be print ASCII value not the natural number.
Because natural no also have same logic and pattern as a know?

System.out.printf("%d : %c \n", i, i); //Error(Its not applicable for the argument String, int, int). I'm using java 8. Can anyone answer, why this line is not executed.
