Parse a Number and Format as Octal in Java

To parse and format a number into octal, try the following code-

Example

public class Demo {
　　　public static void main(String args[]) {
　　　　　　int val = Integer.parseInt("150",　8);
　　　　　　System.out.println(val);
　　　　　　String str = Integer.toString(val,　8);
　　　　　　System.out.println(str);
　　　}
}

Output Result

104
150

In the above program, we used Integer.parseInt() and Integer.toString() methods to convert numbers to octal.

int val = Integer.parseInt("150",　8);
String str = Integer.toString(val,　8);

toString()The above method represents a value as a string and format.

We set the base to8because octal uses a base8Representation.
