If you change the contents of a String object, you are in effect creating a new String object. This might seem a bad idea until you realize that making String objects immutableis done for efficiency reasons. String objects are constant because of their immutability and as such String objects can be shared. This is done by checking the contents of n...
We spoke above of how String objects we create are placed within their own area of The Heap known as the String constant pool. Thisisn't the fully story though. All the String objects we created above were created from string literals, without any mention of the new operator. The String object has many differentconstructors and using them can impac...
The table below shows the declarations of the methods in the Stringclass we cover in this lesson: We will go through the above String methods in this lesson. Use the link below for more information on the other String methods, and there are a lot, available in the Stringclass that are not covered here.
The charAt() method will return the character at the specified index position of the invoking string. The following code and screenshot shows examples of using the String class charAt()method: As you can see from the screenshot the class printed a to the console. Indexes in Java are zero-based, so the outpur is correct. The program then abended wit...
The concat() method will return a String object of the invoking string value appended with the argument string value. The following code and screenshot shows an example of using the String class concat()method: As you can see from the screenshot the class printed javaTutor to the console, which is the result of the concatenation of the String objec...
The equals() method will return true if the invoking string has the the same character sequence as the argument string. This method is a valid override of the Objectsuperclass equals() method. The following code and screenshot shows examples of using the String class equals()method: The screenshot above shows the results of running the TestEquals c...
The length() method will return the length of the invoking string. The following code and screenshot shows an example of using the String class length()method: The screenshot above shows the results of running the TestLength class. We are using the length() method for our loop condition. This way we can ensure we never go past the end of our string...
The replace() method will return a String object of the invoking string value where any occurrences of the first argument char value are replaced with occurrences of the second argument charvalue. The following code and screenshot shows an example of using the String class replace()method: As you can see from the screenshot the class printed jivi5 ...
The toString() method will returns a string description of the object which is the value of the invoking string. This method is a valid override of the Objectsuperclass toString() method. The following code and screenshot shows examples of using the String class toString()method: The screenshot above shows the results of running the TestToString cl...
