The output function of Java is very simple, just call the print function of the out object of the System class directly.
There are four types of output statements in Java:
System.out.println(1111);//Newline printing
System.out.print(1111);//Print without line breaks
System.out.write(2222);//Byte output
System.out.printf("% 8.3f\n", 3.14);//Output according to format
System.out.println(); is the most commonly used Output statement, it will convert the content in brackets into a string and output it to the output window (console), and wrap the line. When the output is a basic data type, it will be automatically converted into a string. If the output is an object , will automatically call the toString(); method of the object and output the return value to the console
System.out.print(); is very similar to the first one, the difference is that there will be a new line after the previous output, and This command does not wrap after output.
System.out.printf(); This method continues the output method of C language and outputs through formatted text and parameter list.
