Java Integer toOctalString() method

The toOctalString() method of Java Integer class returns a string representing the specified int argument as an unsigned integer in base 8. Syntax public static String toOctalString (int  i) Parameters The parameter ‘i’ represents an integer to be converted to a string. Return Value This method returns the string which represents the unsigned integer value of the argument in octal i.e. base 8. Example 1

public class JavaIntegerToOctalStringExample1 {
    public static void main(String[] args) {
        Integer val=2;
        String val1=Integer.toOctalString(val);
        //It returns a string representation of the integer argument as an unsigned integer in base 8
        System.out.println("Octal String : "+val1);

    }
}

Output

Octal String : 2

Example 2

public class JavaIntegerToOctalStringExample2 {
    public static void main(String[] args) {
        //passing negative value
        Integer val=-98623;
        String val1=Integer.toOctalString(val);
        //It returns a string representation of the integer argument as an unsigned integer in base 8
        System.out.println("Octal String : "+val1);
    }
}

Output

Octal String : 37777477301

Example 3

public class JavaIntegerToOctalStringExample3 {
    public static void main(String[] args) {
        //passing the minimum value
        Integer val=Integer.MIN_VALUE;
        String val1=Integer.toOctalString(val);
        //It returns a string representation of the integer argument as an unsigned integer in base 8
        System.out.println("Octal String : "+val1);
    }
}

Output

Octal String : 20000000000

Example 4

public class JavaIntegerToOctalStringExample4 {
    public static void main(String[] args) {
        //passing maximum value
        Integer val=Integer.MAX_VALUE;
        String val1=Integer.toOctalString(val);
        //It returns a string representation of the integer argument as an unsigned integer in base 8
        System.out.println("Octal String : "+val1);
    }
}

Output

Octal String : 17777777777
