Remember that chars in Java are just a special version of ints. Cast the char as an int and you get the Unicode value for it. Fortunately, the group of characters including letters and numbers have the same value in both encoding systems.
for (char letter = 'a'; letter <= 'z'; ++letter) {
System.out.println("ASCII of " + letter + " = " + (int) letter);
}
In order to print a character using its ASCII value, you need to first assign it to a char value like this: char c = (char) 65; In this example, we are casting the int 65 to a char, which converts it to an 'A', since 65 is the ASCII value for the capital letter 'a'. Next, you can print it out if you want: System.out.println(c); That's pretty much all there is to it!
char a = 'A'; System.out.println((int)a);
ASCII and Java are 2 totally different things. ASCII is a naming convention where a certain letter, number, or punctuation mark is a specific keyboard code (Carriage Return, CR, is code 31, Line Feed 14, Capital A 96). Java is a programming language that handles text in multiple formats as needed, Unicode, EBDIC, ASCII. The two are not intertwined.
The Java console is a display of output sent by a Java program. This is similar to the MS DOS operating system.To print to the console, a programmer will type "println(text);" or "print(text);" depending is the programmer wants to make a new line after the text(println) or not(print).
It depends on what you mean by "convert an int to char". If you simply want to cast the value in the int, you can cast it using Java's typecast notation: int i = 97; // 97 is 'a' in ASCII char c = (char) i; // c is now 'a' If you mean transforming the integer 1 into the character '1', you can do it like this: if (i >= 0 && i <= 9) { char c = Character.forDigit(i, 10); .... }

If you look up the ASCII values for digits, you'll see that 0 = 48, 1 = 49... 9 = 57. So it's a simple matter of adding 48 to your digit to find out the ASCII value for it.

#!/usr/bin/perl print 'java program';
look at the print
For(int I = 0: I < 5; i++) { System.out.println(" print this " + I ); }

You cannot do that. The main method of a java class is the point where the execution begins. You can print messages only after a main method is invoked.
in java, char consumes two bytes because it uses unicode instead of ascii. and int takes 4 bytes because 32-bit no will be taken
