Are you finding it difficult to differentiate between the .length and .length() methods? Don't worry, this guide will explain the differences between the two and how you can use them in Java programming.
Understanding the .length Method
The .length method is a member of the String class. It is used to find out the length of a string without any additional arguments. It is not a method, but an attribute or property of a string.
Understanding the .length() Method
The .length() is a method of the String class in Java, which is different from the .length attribute. This method takes in a single argument, the string to be checked. The command returns an integer value representing the length of the targeted string.
Key Differences
Now that you are aware of the basics of the two methods, let's take a look at the key differences between the two. They are as follows:
Usage: The .length() method is a function that requires the string to be passed as an argument, whereas the .length attribute does not require the string to be passed as an argument.
Return Value: The .length() method returns the length of the string passed as an argument. The .length attribute returns the length of the string object.
Data Type:The .length attribute returns an integer value while the .length() method returns a long value.
FAQ
What is the syntax of the .length() method?
The syntax of the .length() method is as follows:
stringObject.length();
What is the return type of the .length() method?
The return type of the .length() method is a long value.
What is the .length method?
The .length method is an attribute of the String class in Java. It is used to find out the length of a string without any additional arguments.
How do you use the .length() method?
To use the .length() method, you must first create a string object. You can then pass the string as an argument to the method. The command will then return an integer value representing the length of the targeted string.
What is the difference between the .length() and .length methods?
The main difference between the two methods is that the .length attribute is used to find out the length of the string object, whereas the .length() method requires the string to be passed as an argument and returns the value of the string. The .length attribute returns an integer value, while the .length() method returns a long value.
Conclusion
.length and .length() are two different methods for finding out the length of a string in Java. While the .length() method requires the string to be passed as an argument and returns the value of the string, the .length attribute does not require the string to be passed as an argument and returns the length of the string object.
We hope this guide was able to help you understand the key differences between the two methods. For more information, you can refer to the official Java documentation.
