Java - Integer Class toOctalString() Method

Integer class toOctalString() method: Here, we are going to learn about the toOctalString() method of Integer class with its syntax and example. By Preeti Jain Last updated : March 18, 2024

Integer class toOctalString() method

• toOctalString() method is available in java.lang package.
• toOctalString() method is used to represent an octal string of the given parameter [value] of integer type as an unsigned integer in base 8.
• toOctalString() method is a static method, it is accessible with class name too and if we try to access the method with the class object then also we will not get an error.
• toOctalString() method does not throw an exception at the time of conversion from integer to an octal string.

Syntax

public static String toOctalString (int value);

Parameters

• int value – represents the integer value to be converted.

Return Value

The return type of this method is int, it returns the octal string of the given parameter that represent the unsigned integer value.

Example

// Java program to demonstrate the example 
// of toOctalString (int value) method of Integer class

public class ToOctalStringOfIntegerClass {
    public static void main(String[] args) {
        // Variables initialization
        int i1 = 10;
        int i2 = 20;
        int i3 = 30;
        int i4 = Integer.MAX_VALUE;
        int i5 = Integer.MIN_VALUE;

        // Integer instance creation
        Integer value = new Integer(i1);

        // It represents Octal string of the given
        // integer type i2 argument
        String s = value.toOctalString(i2);

        // Display Octal String Representation
        System.out.println("value.toOctalString(i2): " + s);

        // It represents Octal string of the given
        // integer type i3 argument
        s = value.toOctalString(i3);

        // Display Octal String Representation
        System.out.println("value.toOctalString(i3): " + s);

        // It represents Octal string of the given
        // integer type i4 argument
        s = value.toOctalString(i4);

        // Display Octal String Representation
        System.out.println("value.toOctalString(i4): " + s);

        // It represents Octal string of the given
        // integer type i5 argument
        s = value.toOctalString(i5);

        // Display Octal String Representation
        System.out.println("value.toOctalString(i5): " + s);
    }
}

Output

value.toOctalString(i2): 24
value.toOctalString(i3): 36
value.toOctalString(i4): 17777777777
value.toOctalString(i5): 20000000000
