# Write a program to multiply two 2d matrices in java

Crashes If you have not already reset your 50g, take your paper clip and reset your 50g using the reset hole on the back of the 50g. Expect to do this frequently. You should only lose the contents of the stack. Crashes are usually caused by yours or someone else's bug. Java program for matrix multiplication Java program for matrix multiplication Write a Java program to multiply two matrices is one of the frequently asked Java coding interview questions for freshers.

In this post we will see Java program for matrix multiplication i. Here is how we need to perform multiplication. The element in the first row first column of matrix A should be multiplied with the element in the first row first column of matrix B.

The element in the first row second column of matrix A should be multiplied with the element in the second row first column of matrix B.

Similarly the element in the first row third column of matrix A should be multiplied with the element in the third row first column of matrix B.

The result of all these multiplication should be added together to get the first element of the resultant matrix.

Similar step has to be followed by taking the elements in first row of matrix A and elements of second column in matrix B. Continue the above steps for second row of matrix A with first column of matrix B and second row of matrix A with second column of matrix B.

In order to multiply two matrices, the number of columns in the first matrix should be equal to the number of rows in the second matrix. Otherwise matrix multiplication cannot be done. Matrix multiplication is not cumulative. Let us see the Java program to multiply two matrices.Task. Multiply two matrices together. They can be of any dimensions, so long as the number of columns of the first matrix is equal to the number of rows of the second matrix.

Output of program: This is a basic method of multiplication, there are more efficient algorithms available. Also this approach isn't recommended for sparse matrices which contains a large number of elements as zero.

International Journal of Engineering Research and Applications (IJERA) is an open access online peer reviewed international journal that publishes research. So I have a code that will print a table of 2 dimensional arrays. The problem that I've run into is that I have absolutely no idea how to multiply .

This is a java program to perform a simple matrix multiplication. For matrix multiplication to happen the column of the first matrix should be equal to the row of the second matrix. Here is the source code of the Java Program to Perform Matrix Multiplication.

The Java program is successfully compiled and run on a Windows system. The program output . This post is an extension of How to dynamically allocate a 2D array in C?. A one dimensional array can be easily passed as a pointer, but syntax for passing a 2D array to a function can be difficult to remember.
