• Underscores in Java and Python numbers

  In some areas in the world people use commas as thousand separators. I sometimes use points to separate them. Most of the time I do not use separators at all. In Python and Java the convention is to use underscores as separators. In this post, I investigate underscores in Java and Python numbers. Underscores in Java numbers The following example is the base example. Print the number one million on the console or terminal. public class Test { public void ItCompiles(){ int million = 1000000; System.out.println("The number is: " + million); } public static void main(String []args){ Test test = new Test(); test.ItCompiles(); } } This compiles and gives as output: The number is: 1000000 It works In java it is possible to have underscores in numbers to make the number easier to read. public void ItCompiles(){ int million = 1_000_000; System.out.println("The number is: " + million); } This example compiles. The output is the same as the first example. The underscores are not printed out. Java allows underscores in numbers to help the programmer with reading his own code. An underscore at the beginning or end is not possible in Java. It is also not possible to have an underscore before and after a decimal point. The following statements are all invalid. int million = _1000000; int million1 = 1000000_; int million2 = 1000._0; int million3 = 1000_.00; I can write some strange things in Java. The following example compiles: int million = 1_0_0_0_0_0_0; That is not very readable.[…]
