Public class IdentifierExpectedExpression IdentifierExpectedDeclaration.java:12: error: expected Moving the statements in question to an appropriate place resolves this error (Fig. When isolated expression statements such as assignments or method invocations appear outside the scope of a constructor, a method, or an instance initialization block, the expected error is raised (Fig. Another common scenario for this error is when a method parameter does not have its data type, or similarly, its name declared. This error typically occurs when an expression statement (as defined in ) is written outside of a constructor, method, or an instance initialization block. The expected error is a very common Java compile-time error faced by novice programmers and people starting to learn the language. When the compiler reaches a point where, according to these rules, an identifier is expected to appear but something else is found instead, it raises the expected error, where the angle brackets denote a reference to a token object. Here is where all tokens, including identifiers, are being checked against a predefined set of grammar rules.

The compiler reads the input code as a stream of characters and categorizes them into lexemes of tokens, before proceeding to parse the tokens into a syntax tree.
The initial phase of the Java compilation process involves lexical analysis of the source code. Identifier Expected Error: What It Is & What Triggers It This allows programmers to use identifiers in programs written in their native languages. An identifier may contain letters and digits from the entire Unicode character set, which supports most writing scripts in use in the world today, including the large sets for Chinese, Japanese, and Korean. An identifier can be used to name a package, a class, an interface, a method, a variable, etc.
Typically, this error occurs when there is an. By definition, an identifier in Java is a sequence of one or more characters, where the first character must be a valid first character (letter, $, _) and each subsequent character in the sequence must be a valid non-first character (letter, digit, $, _). The class interface or enum expected error is a compile-time error in Java which arises due to curly braces.
