There are four types of output statements in Java:

System.out.println(1111);//换行打印
System.out.print(1111);//不换行打印
System.out.write(2222);//字节输出
System.out.printf("%+8.3f\n", 3.14);//按格式输出

System.out.println(); is the most commonly used output statement, which converts the content in brackets into string output Go 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, the toString(); method of the object will be automatically called and the return value will be output. Go to the console

System.out.print(); Very similar to the first one, the difference is that the previous output will have a newline, but this command will not have a newline after the output.

System.out.printf(); This method continues the output method of C language and outputs through formatted text and parameter list.
