Java Primitive Array To Wrapper Array | The wrapper classes in Java are used to convert primitive datatype to object and object into primitive datatype. The conversion of primitive datatype to an object is called autoboxing and converting an object to primitive datatype is called unboxing. The feature autoboxing and unboxing in java is used […]

Java Print Array Without Brackets | In this section, we print the array without brackets and commas to do this we use replace() method and the Arrays.toString() method available in Java. See the below examples to understand the problem:- 1) array[ ] = {1, 2, 3, 4, 5}Print array without brackets:-1, 2, 3, 4, 5

How to Print Arraylist Without Brackets Java | In this case, we print the array list without brackets, usually when we use ArrayList the elements are printed within the brackets. To do this we can use replace method which replaces the brackets by space. Now see some below examples to get to the know the

Java Array of Random Numbers | In order to generate random integer elements, we use the nextInt() method available in the Java Random class. To use this method we need to import the Random class as import java.util.Random then creates an object and then calls it with nextInt() so it generates some random numbers. Java

Java Magic Square 2d Array | A magic square is a matrix that has a different integer, the sum of a number in every row, column, and diagonally is the same. This sum value is called a magic constant. The formula to find the magic constant is M = n[(n^2+1) / 2] Where, n =

How to Check if Array has Same Values Java | In this section, we will check whether the two arrays have the same elements or not. The elements may be in a different order or at different indexes but the elements need to be the same. For more detail see the below example:- 1) int

Check if all elements in an Array are Equal Java | Here, the problem is to check whether all the elements in an array are equal or not. As we just need to check the elements in the given array, therefore there is no need to compare between two or more arrays. Hence to solve

Java Count Occurrences in 2D Array | In this section, we will count the occurrences of the element in the two-dimensional array that is we count the number of occurrences in the matrix. To display the matrix we use Arrays.deepToString() method this method is used for converting multidimensional arrays to strings. To know more about
