How to replace a character in a String with another character

There is a replace method provided by the String class that can be used to replace a character in a String with another character. The following code snippet demonstrates this:

 

package demo;public class StringDemo {public static void main(String[] args) {String str = "Hello World";String modifiedStr = str.replace('o', 'i');System.out.println("Modified String is "+modifiedStr);}}

 

 
So the above code will replace all occurrences of the letter ‘o’ in the String “Hello World”  an ‘i’ and will print the following:

Java 8 DoubleFunction Example





















In this blog post, I will be explaining how the Java 8 functional interface DoubleFunction  works. To know more about functional interfaces, you can refer  this  blog post. Edit 	     The   DoubleFunction  interface provides a method called apply . It accepts a single parameter of double data type. It returns a result of any data type. So it basically applies the logic in the apply method to the input parameter and returns the result. The DoubleFunction interface is a specialization of the Function  interface. While the Function  interface accepts any data type, the DoubleFunction interface accepts a long value. To see an example of the Function  interface, refer to  this  blog post. DoubleFunction Interface that returns an Integer Consider the following code snippet: DoubleFunction<Integer> integerRetriever = input -> new Double(input).intValue();Double input = 4.8;System.out.println("Integer Value "+integerRetriever.apply(input) );   Here, we have written a   Doubl...

How to convert a List to a Set





















In this blog post ,I will be showing you how you can convert a List to a Set. Consider the following code snippet: public class ListToSetDemo {public static void main(String[] args) {List<Integer> list = Arrays.asList(5,3,11,15,9);//Method 1Set<Integer> set = new HashSet<Integer>(list);System.out.println("Set is "+set);//method 2Set<Integer> set2 = new HashSet<Integer>();set2.addAll(list);System.out.println("Set is "+set2);}} This code demonstrates two ways to convert a List to a Set. Method 1 Here, we are creating a new HashSet . We are invoking the constructor  that accepts a Collection object. Here, we are passing in the input list to this constructor.   Method 2 Here again, we are creating a new HashSet . However, we are using the default constructor. We are then invoking the addAll  method and passing in the input list.   When you run this code, it will print the following output: Set is [3, 5, 9, 11, 15]Set is [3, 5, 9, 1...

ArrayList Vs LinkedList





















In this blog post, I will be comparing the ArrayList  and LinkedList  classes. I will be explaining how they are similar, how they are different and when you should use which.   Similarities: Both are Collections and implement the List  interface Both are used to store a dynamic number of elements (Primitive or Object type) Differences ArrayList uses an array data structure internally to store the data. A LinkedList on the other hand, uses a doubly linked list internally as the data structure to store data. If you are not familiar with what a Linked List data structure is, you can refer this link . When you need to insert or delete data from the bottom of the List, an ArrayList is faster. If you need to insert or delete an element from the middle of the list,  a LinkedList is faster. An ArrayList  uses an array to store the data internally. So when you insert or delete an element from the bottom of the list, this does not affect the array. However if you insert or delete an element...
