Priority 1 operators

()	x(y)	Method call operator
new	new int()	new operator

The method call operator is an operation to call a method.

int i = 10;

string result = i.ToString() + " is 10."; // The result is "10 is 10."

The method call operator creates a signature from the method name and arguments, and calls appropriate method.

As the above example, if there is the dot operator before the method name, the method call operator calls the method of the instance returned by the dot operator. Otherwise, calls a method of the current instance.

A method call as an expression must return an instance. An exception will be thrown if you call a method with no return value as an expression.

The new operator gets an instance of the class specified by the fitter. The instance will be initialized with a fitter.

int i = new int(10); // 10.

You can get an instance of the desired class since the fitter name is the same as the class name.

The this operator gets the current instance.

The indexer operator accesses an item of the list class.

The left operand of the operator must return the list class. The expression between [] must return the int class.

list il = new list("{100,101,102,103}"); // 100, 101, 102, 103

int i = il[0]; // i is 100.

i = il[1]; // i is 101.

If the indexer operator appears on the left of the assignment statement, you can assign to the item of the list.

il[0] = 1000; // il is 1000, 101, 102, 103.
