Example: Find ASCII value of a character

public class AsciiValue {

    public static void main(String[] args) {

        char ch = 'a';
        int ascii = ch;
        // You can also cast char to int
        int castAscii = (int) ch;

        System.out.println("The ASCII value of " + ch + " is: " + ascii);
        System.out.println("The ASCII value of " + ch + " is: " + castAscii);
    }
}

Output

The ASCII value of a is: 97
The ASCII value of a is: 97

Example: How to Print an Integer entered by an user:

import java.util.Scanner;

public class HelloWorld {

    public static void main(String[] args) {

        // Creates a reader instance which takes
        // input from standard input - keyboard
        Scanner reader = new Scanner(System.in);
        System.out.print("Enter a number: ");

        // nextInt() reads the next integer from the keyboard
        int number = reader.nextInt();

        // println() prints the following line to the output screen
        System.out.println("You entered: " + number);
    }
}

Output

Enter a number: 10
You entered: 10

The least common multiple (L.C.M.) of two numbers is the smallest positive integer that is perfectly divisible by the two given numbers.

For example, the L.C.M. of 12 and 14 is 84.

The highest common factor (H.C.F) or greatest common divisor (G.C.D) of two numbers is the largest positive integer that perfectly divides the two given numbers. For example, the H.C.F of 12 and 14 is 2.

The user needs to press ENTER to complete each lap. The timer keeps counting till CTRL+SHIFT is pressed.For each lap we calculate the lap time by subtracting the current time from the total time at the end of the previous lap. The time() function of the time module, returns the current epoch time in milliseconds.

To delete a file with this script, we can use the os module.It’s recommended to check with a conditional if the file exist before calling the remove() function from the module:

import os

if os.path.exists("<file_path>"):
  os.remove("<file_path>")
else:

To replace the content completely, we use the "r" mode, so we pass this string as the second argument to open(). We call the .write() method on the file object passing the content that we want to write as argument.

For example:

words = ["Blue", "Amazing", "Python", "Code"]

with open("famous_places.txt", "r") as file:
    for word in words:
        file.write(word + "\n")
