In Java,
the category interface or enum expected error
may be a compile-time error. There
are often one among the subsequent reasons we get “class, interface, or enum expected” error in
Java:
Case 1: Extra curly Bracket
class Hello {
public static void main(String[] args)
{
System.out.println("Helloworld");
}
}
} // extra bracket.
In this case, the error can be corrected simply by removing the additional bracket.
class Hello {
public static void main(String[] args)
{
System.out.println("Helloworld");
}
}
Case 2: Function outside the class
class Hello {
public static void main(String args[])
{
System.out.println("HI");
}
}
public static void func() { System.out.println("Hello"); }
In the previous example, we got an error because the method func() is outside the Hello class. You can delete it by moving the closing brace "}" to the end of the file. In other words, move the func() method to Hello.
class Hello {
public static void main(String args[])
{
System.out.println("HI");
}
public static void func()
{
System.out.println("Hello");
}
}
Case 3: Forgot to declare class at all
There could be an opportunity that we forgot to declare class in the least . we'll get this error. Check if you've got declared class, interface, or enum in your java file or not.
Case 4: Declaring more than one package in the same file
package A;
class A {
void fun1() { System.out.println("Hello"); }
}
package B; //getting class interface or enum expected
public class B {
public static void main(String[] args)
{
System.out.println("HI");
}
}
We can not put different packages into an equivalent source file. within the source file, the package statement should be the primary line.
package A;
class A {
void fun1() { System.out.println("Hello"); }
}
public class B {
public static void main(String[] args)
{
System.out.println("HI");
}
