List of situations that cause a NullPointerException to occur

Here are all the situations in which a NullPointerException occurs, that are directly* mentioned by the Java Language Specification:

• Accessing an instance field of a null reference.
• Calling an instance method of a null reference.
• throw null;
• Accessing elements of a null array.
• Synchronising on null - synchronized (someNullReference) { ... }
• Any integer/floating point operator can throw a NullPointerException if one of its operands is a boxed null reference
• An unboxing conversion throws a NullPointerException if the boxed value is null.
• Calling super on a null reference throws a NullPointerException.
• Using a for (element : iterable) loop to loop through a null collection/array.
• switch (foo) { ... } (whether its an expression or statement) can throw a NullPointerException when foo is null.
• foo.new SomeInnerClass() throws a NullPointerException when foo is null.
• Method references of the form name1::name2 or primaryExpression::name throws a NullPointerException when evaluated when name1 or primaryExpression evaluates to null.
