Because it doesn't match any of the syntax constructions given in
the Java Language Specification referenced above (learn to read):
LocalVariableDeclarationStatement
ClassDeclaration
Statement
Your statement |Test.x;| is obviously not a local variable
declaration nor class declaration, further:
Statement:
StatementWithoutTrailingSubstatement
LabeledStatement
IfThenStatement
IfThenElseStatement
WhileStatement
ForStatement
Yours is none of labeled, if-then, if-then-else, while or for
statement, so:
StatementWithoutTrailingSubstatement:
Block
EmptyStatement
ExpressionStatement
AssertStatement
SwitchStatement
DoStatement
BreakStatement
ContinueStatement
ReturnStatement
SynchronizedStatement
ThrowStatement
TryStatement
The only posibility here is expression statement:
ExpressionStatement:
StatementExpression ;
StatementExpression:
Assignment
PreIncrementExpression
PreDecrementExpression
PostIncrementExpression
PostDecrementExpression
MethodInvocation
ClassInstanceCreationExpression
Which of the given above should match your statement? Yours is
neither assignment nor pre-increment, nor pre-decrement, nor
post-increment, nor post-decrement, nor method invocation, nor
class instance creation.
