Decimal to Octal Converter()

Step 1: Understand the Problem

In order to convert a decimal number to an octal number, we need to divide the decimal number by 8 and store the remainder. We continue this process until the quotient is less than 8. The octal number is the sequence of remainders in the reverse order.

Step 2: Declare the Function

We will write a Java function named decimalToOctal that takes a decimal number as an input parameter. This function will return the octal equivalent of the decimal number.

public static int decimalToOctal(int decimal)
{
}

Step 3: Implement the Conversion Logic

Inside the decimalToOctal function, we will implement the logic for converting decimal to octal.

public static int decimalToOctal(int decimal)
{
    int octal = 0, counter = 0;
    while(decimal > 0)
    {
        int remainder = decimal % 8;
        decimal /= 8;
        octal += remainder * Math.pow(10, counter);
        counter++;
    }
    return octal;
}

Step 4: Test the Function

We will test our function with some decimal numbers to make sure that it is working correctly.

decimalToOctal(10); // should return 12
decimalToOctal(8); // should return 10
decimalToOctal(18); // should return 22

Conclusion

From this, we have successfully written a Java function to convert a decimal number to an octal number. This function is simple and takes a general approach to solve the problem.

public static int decimalToOctal(int decimal)
{
    int octal = 0, counter = 0;
    while(decimal > 0)
    {
        int remainder = decimal % 8;
        decimal /= 8;
        octal += remainder * Math.pow(10, counter);
        counter++;
    }
    return octal;
}
