Java Program to Create random strings
In this article, we will understand how to create random strings. String is a datatype that contains one or more characters and is enclosed in double quotes(“ ”).Below is a demonstration of the same −Suppose our input is −The size of the string is defined as: 10The desired output would be −Random string: ink1n1dodvAlgorithmStep 1 - START Step 2 - Declare an integer namely string_size, a string namely alpha_numeric and an object of StringBuilder namely string_builder. Step 3 - Define the values. Step 4 - Iterate for 10 times usinf a for-loop, generate a random value using the function Math.random() ...

In this article, we will understand how to find the trace and normal of a given matrix. The normal of a matrix is the square root of the sum of squares of all the elements of a matrix. The trace of a matrix is the sum of all the elements present in the principal diagonal (upper left to lower right).Below is a demonstration of the same −Suppose our input is −The matrix is defined as: 2 3 4 5 2 3 4 6 9The desired output would be −Trace value: 13.0 Normal value: 14.142135623730951AlgorithmStep 1 - START Step 2 - ...
Read MoreJava Program to Interchange Elements of First and Last in a Matrix Across Rows
In this article, we will understand how to interchange elements of first and last in a matrix across rows. The matrix has a row and column arrangement of its elements. A matrix with m rows and n columns can be called as m × n matrix.Individual entries in the matrix are called element and can be represented by a[i][j] which suggests that the element a is present in the ith row and jth column.Below is a demonstration of the same −Suppose our input is −The matrix is defined as: 4 5 6 7 1 7 3 4 11 12 13 ...
