In this post, we will see how to initialize a list in Java in single line with specified value. Get great deals at Amazon
We have already covered how to flatten a Stream using flatMap() and concat() methods in Java 8. In this post, we will flatten a Stream in Java 8 using Stream.forEach() method.
In this post, we will discuss how to shuffle or randomize a List in Java using Fisher–Yates shuffle algorithm and shuffle() method provided by the Collections class.
In this post, we will see how to clone a List in Java. We need to construct a list containing the elements of the specified list, in the same order as the original list. Assume there are no mutable objects in the list. i.e. the code can perform a shallow copy.
Java 8 Streams can holds different types of data. For example, Stream<T>, Stream<T>, Stream<List<T>> – all these are valid streams in Java 8. We have seen in the previous post that flatMap() method can be used for flattening Streams in Java. In this post, we will flatten Stream of Arrays or Lists using Stream.concat() method …
In this post, we will discuss flatMap() method in Java which is used to flatten Streams in Java.
In this post, we will discuss how to generate an IntStream in decreasing order. In other words, generate integers in specified range from high to low using Streams in Java.
In this post, we will see how to capitalize first character of each word in a given text.
Stream API is the most important addition in Java 8. In this post, we will discuss various ways to create a Stream in Java.
Given a Java Collection, construct a new String containing string representation of its elements separated by the specified delimiter.
In this post, we will see how to reverse a List in Java by modifying the list in-place. That means that the conversion should take place without using any auxiliary list, by overwriting the existing elements of the specified list. Assume that the specified list is modifiable. For immutable lists, an UnsupportedOperationException should be …
In this post, we will see how to reverse elements of a parallel Stream in Java. In other words, we’ll create a new Stream which iterates the elements of specified stream in reverse order.
