Python program to pad zeroes to a string
In this python programming tutorial, we will learn how to pad extra zeros to a string. For example, if the string is 2, and if we pad three zeros to this string, it will become 0002. Similarly, we can pad zeros to any type of string like 00Hello or 000world. We can pad any number of zeros to a string.

ReadDart list : Explanation with example
List or array of similar items is used in all programming languages.In dart, this is represented by array or commonly known as lists. List is an ordered group of objects. The index of the list starts from 0.So, the index of the first element is 0,second element is 1 etc. Using this index,we can access any value for a specific position in the list.Creating a simple looks like as below :.
ReadDart example program to iterate through a list
In this tutorial, we will learn how to iterate through a list of items in dart. List holds items of similar type.

ReadJava strictfp keyword : Explanation with example
strictfp keyword is used for getting the same result of floating point calculation on different platforms. We cannot use strictfp with a class constructor or with methods defined inside an interface. But we can define an interface as strictfp and then all the methods defined inside that interface will become strictfp automatically. Similarly, we can use strictfp for class and methods also.
