Java Program to display the upper triangular matrix
public class UpperTriangular
{
public static void main(String[] args) {
int rows, cols;
//Initialize matrix a
int a[][] = {
{1, 2, 3},
{8, 6, 4},
{4, 5, 6}
};
//Calculates number of rows and columns present in given matrix
rows = a.length;
cols = a[0].length;
if(rows != cols){
System.out.println("Matrix should be a square matrix");
}
else {
//Performs required operation to convert given matrix into upper triangular matrix
System.out.println("Upper triangular matrix: ");
for(int i = 0; i < rows; i++){
for(int j = 0; j < cols; j++){
if(i > j)
System.out.print("0 ");
else
System.out.print(a[i][j] + " ");
}
System.out.println();
}
}
}
}
Output:
Upper triangular matrix:
1 2 3
0 6 4
0 0 0
