Write a Java Program to Convert Octal Number to Decimal and vice-versa
PROGRAM: Java Program to Convert Octal Number to Decimal and vice-versa
/*Java Program to Convert Octal Number to Decimal and vice-versa*/
1: Program to Convert Octal to Decimal
public class OctalDecimal {
public static void main(String[] args) {
int octal = 116;
int decimal = convertOctalToDecimal(octal);
System.out.printf(“%d in octal = %d in decimal”, octal, decimal);
}
public static int convertOctalToDecimal(int octal)
{
int decimalNumber = 0, i = 0;
while(octal != 0)
{
decimalNumber += (octal % 10) * Math.pow(8, i);
++i;
octal/=10;
}
return decimalNumber;
}
}
2: Program to Convert Decimal to Octal
public class DecimalOctal {
public 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;
}
}
