throwing bug value

Hi People, this program throwing bug value. it should print out whatever i give it as input.
anything woring i am doing?

public class Hello {
public static void main( String args[])
{


int j;
try {
j = System.in.read();
System.out.print(j);
} catch (IOException e) {

System.out.println("error");
}}

read() is not doing what you want there. It's read the next cumming/finding byte of a stream. That byte print as an int value, so that's why you get a bug value. Read the Java docs for more details.

To read the user inputs use Scanner class.

It is. All the keys on a keyboard send an integer to the input handlers. To get that integer as a character, you need to use some conversion program/technique to convert it to a char or String.
For example the integer value of the character 'a' is 0x61 0r 97. Is that what you see with your program when you type in an 'a' (without 's)?
To convert an int to a char, you can cast it:
println("j=" + (char)j);

Like this.

Code:

---

        int j;
        try {
            j = System.in.read();
            System.out.println((char)j);
        }
        catch(Exception e) {
            e.printStackTrace();
        }
