Unlock the Power of Java: Mastering Number Conversions
Getting Started with Java Methods and Operators
To grasp the concepts of number conversions in Java, it’s essential to have a solid understanding of Java methods and operators. These building blocks of Java programming enable you to write efficient and effective code.
Converting Decimal to Octal: A Step-by-Step Guide
When converting decimal numbers to octal, a specific process takes place. Let’s break it down:
First, the decimal number is divided by 8, and the remainder is noted. This process is repeated until the quotient becomes 0. The remainders are then arranged in reverse order to form the octal equivalent.
Example 1: Putting it into Practice
Here’s a Java program that demonstrates the conversion of decimal to octal:
“`java
import java.util.Scanner;
public class DecimalToOctal {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print(“Enter a decimal number: “);
int decimal = scanner.nextInt();
String octal = Integer.toOctalString(decimal);
System.out.println(“The octal equivalent is: ” + octal);
}
}
“`
The Reverse Process: Converting Octal to Decimal
Conversely, when converting octal numbers to decimal, each digit of the octal number is multiplied by a power of 8, depending on its position. The resulting products are then added together to form the decimal equivalent.
Example 2: Converting Octal to Decimal
Here’s a Java program that demonstrates the conversion of octal to decimal:
“`java
import java.util.Scanner;
public class OctalToDecimal {
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
System.out.print(“Enter an octal number: “);
String octal = scanner.next();
int decimal = Integer.parseInt(octal, 8);
System.out.println(“The decimal equivalent is: ” + decimal);
}
}
“`
