In this question, we will see how to input numbers in a 3X3 integer matrix (2d array) and print the largest numbers in each row in Java programming. To know more about two dimensional array click on the two dimensional array lesson.
Q9) Write a program in Java to input numbers in a 3X3 integer matrix (2d array) and print the largest number in each row.
Program
import java.util.Scanner;
public class Q9
{
public static void main(String args[])
{
int a[][]=new int[3][3], r,c,lg=0,x=0;
Scanner sc=new Scanner(System.in);
System.out.println("Enter 9 numbers");
for(r=0; r<3; r++)
{
for(c=0; c<3; c++)
{
a[r][c]=sc.nextInt();
}
}
for(r=0; r<3; r++)
{
x=0;
for(c=0; c<3; c++)
{
System.out.print(a[r][c]+" ");
if(x==0)
{
lg=a[r][c];
x=1;
}
else if(a[r][c]>lg)
{
lg=a[r][c];
}
}
System.out.println(" Largest Number = "+lg);
}
}
}Output
Enter 9 numbers 18 12 5 10 15 45 38 72 64 18 12 5 Largest Number = 18 10 15 45 Largest Number = 45 38 72 64 Largest Number = 72
