So please let me what will be right right. Is String or int or what is it? It is nothing but a PrintStream. Just open the java. System API doc and we can see that variable declared in that class.

This method is sometimes called the print line method. In addition to printing to console, the println method moves the cursor to a new line. The PrintStream class contains the print and the println methods. These methods are overloaded. So, System. We can then call the print or println method on this instance variable.

Another thing to note is that the argument passed to the method is evaluated from left to right. So if the first two variables passed are integers, then normal arithmetic addition takes place, and the result of addition is concatenated with the string. We can apply the rule shown below from left to right to compute the output.

If no strings are present, then normal arithmetic addition takes place. The print and println methods implicitly call the toString method on the argument. It converts the argument into a string. This is very useful if we want to print user-defined class instances in a particular way.

We can override the toString method in our class to print our object in different formats. How setting an Object to null help Garbage Collection?
