A Matrix is a rectangular array. The elements are arranged in the rows and columns. In this tutorial, we will look at some matrix programs in Java. Graphical Representation of Matrix Matrix in Java We can implement a matrix using two dimensional array in Java. The element at row “r” and column “c” can be […]

Command-line arguments in Java are used to pass arguments to the main program. If you look at the Java main method syntax, it accepts String array as an argument. When we pass command-line arguments, they are treated as strings and passed to the main function in the string array argument. The arguments have to be […]

Relational Operators in Java Java has 6 relational operators. == is the equality operator. This returns true if both the operands are referring to the […]

Java List removeAll() method removes all of its elements that are also present in the given list. The method throws UnsupportedOperationException if the operation is not supported by the list. If the given collection is null, NullPointerException is thrown. This method returns true if the list is changed, otherwise false. Java List removeAll() Examples Let’s […]

Java List remove() method is used to remove elements from the list. ArrayList is the most widely used implementation of the List interface, so the examples here will use ArrayList remove() methods. Java List remove() Methods There are two remove() methods to remove elements from the List. E remove(int index): This method removes the element […]

Java Stream distinct() method returns a new stream of distinct elements. It’s useful in removing duplicate elements from the collection before processing them. Java Stream distinct() Method The elements are compared using the equals() method. So it’s necessary that the stream elements have proper implementation of equals() method. If the stream is ordered, the encounter […]

Java Stream forEach() and forEachOrdered() are terminal operations. The forEach() method is used to perform an action on each elements of the stream. If the forEach() method is used with parallel stream, the encounter order is not maintained. The action will be performed on each element, but their order will not be fixed. If you […]

Java Modulo operator or modulus operator is used to getting the remainder when we divide an integer with another integer. Java Modulo Operator Syntax The % character is the modulus operator in Java. Its syntax is: int remainder = int % int The modulus operator always returns an integer. If we try to use the […]
