Declaration
Following is the declaration for java.lang.Enum.ordinal() method
public final int ordinal()
Parameters
NA
Return Value
This method returns the ordinal of this enumeration constant.
Exception
NA
Example 1
The following example shows the usage of ordinal() method for an enum using its reference.
package com.tutorialspoint; // enum showing topics covered under Tutorials enum Tutorials { Java, HTML, Python; } public class EnumDemo { public static void main(String args[]) { Tutorials t1, t2, t3; t1 = Tutorials.Java; t2 = Tutorials.HTML; t3 = Tutorials.Python; // returns the ordinal corresponding to an enum System.out.println(t1.ordinal()); System.out.println(t2.ordinal()); System.out.println(t3.ordinal()); } }
Output
Let us compile and run the above program, this will produce the following result −
0 1 2
Example 2
The following example shows the usage of ordinal() method for an enum using its type directly.
package com.tutorialspoint; // enum showing topics covered under Tutorials enum Tutorials { Java, HTML, Python; } public class EnumDemo { public static void main(String args[]) { // returns the ordinal corresponding to an enum System.out.println(Tutorials.Java.ordinal()); System.out.println(Tutorials.HTML.ordinal()); System.out.println(Tutorials.Python.ordinal()); } }
Output
Let us compile and run the above program, this will produce the following result −
0 1 2
