Answer 1

Answer:

static void main(String[] args) {

int decimal = 78;

int octal = convertDecimalToOctal(decimal);

System.out.printf("%d in decimal = %d in octal", decimal, octal);

}

public static int convertDecimalToOctal(int decimal)

{

int octalNumber = 0, i = 1;

while (decimal != 0)

{

octalNumber += (decimal % 8) * i;

decimal /= 8;

i *= 10;

}

return octalNumber;
