Java中一般用Integer.parseInt()来将一个字符串转换为int型。但是二者之间还是有很大的区别，就会导致移植的代码功能不完全相同。本来想到网上找一个现成的用Java语言写的与atoi功能相同的方法，但是没有找到，于是干脆凭着自己对atoi的了解写了一个。

The C library function int atoi(const char *str) converts the string argument str to an integer (type int). Declaration.

myMethod () is the name of the method static means that the method belongs to the Main class and not an object of the Main class. You will learn more about objects and how to access methods through objects later in this tutorial. void means that this method does not have a return value.

Generic methods allow type parameters to be used to express dependencies among the types of one or more arguments to a method and/or its return type. If there isn't such a dependency, a generic method should not be used. It is possible to use both generic methods and wildcards in tandem. Here is the method Collections.copy():

The toString() method returns the string representation of the object. If you print any object, java compiler internally invokes the toString() method on the object. So overriding the toString() method, returns the desired output, it can be the state of an object etc. depends on your implementation. Advantage of Java toString() method

Return Value. This function returns the converted integral number as an int value. myMethod () is the name of the method static means that the method belongs to the Main class and not an object of the Main class.
