Object#tostring ():Object object = getObject (); System.out.println (Object.ToString ());In this method of use, because the public method is already in the Java.lang.Object class. ToString (), this method can be called for any Java object that is strictly meaningful. Note, however, that object must be guaranteed to be not a null value, otherwise the NullPointerException exception will be thrown. With this approach, the derived class typically overrides the ToString () method in object.(

The connector--point, itself is also an operator. Its real name should be called the "character operator." The function is to connect two strings together.echo character. Variable. Characters
The dot number connects the three values to one and runs normally.
Cases:
1. String + variable + string
Echo ("

2. Variables + variablesEcho ($result. $result);

String is one of the core classes in java programming language. It is widely used and widely used.But do you know what is the direct string volume? Do you know there is a string resident pool? The string resident pool can be used to cache the direct string volume.

Function Requirement: input a string "1-2-3" to cut out "1", "2", and "3 ". Use the string split function in Java. The string in C ++ does not directly provide this function. You need to write it yourself.

Objective:Almost all applications on a computer use string data as the processing object, however, the hardware structure of the computer we are using today is primarily reflective of the need for numerical computation, so it is much more complex to process string data than to process integers and floating-point numbers. Moreover, in different types of applications, the strings handled have different charac
For the mechanism of creating a string object, what is involved in this process is worth exploring.Let's look at the following code to see how the new String object differs from the direct assignment: Public Static voidMain (string[] args) {String str1=NewString ("ABC"); String
