c to java programming

[fong luan]

dear readers,

i hope any of u can help me to figure out how to create a matrix
multiplier program in java applet. i hope some of u would answer to my
question. thanks.

below i also posted my matrix program which is in c language as a
reference


#include<stdio.h>

#define MAXROWS 20
#define MAXCOLS 30
void readinput(int a[][MAXCOLS], int nrows, int ncols);
void computemultiply(int a[][MAXCOLS],int b[][MAXCOLS],int c[]
[MAXCOLS],int nrows,int ncols);
void writeoutput(int c[][MAXCOLS],int nrows, int ncols);

main()
{
int nrowa, ncola,nrowb, ncolb;
/*array definitions*/
int a[MAXROWS][MAXCOLS]=0;
int b[MAXROWS][MAXCOLS]=0;
int c[MAXROWS][MAXCOLS]=0;

printf("How many rows for matrix a?\n");
scanf("%d",&nrowa);
printf("How many columns for matrix b?\n");
scanf("%d",&ncola);

printf("How many rows for matrix b?");
scanf("%d",&nrowb);
printf("How many columns for matrix b?");
scanf("%d",&ncolb);

printf("\n\nFirst table:\n");
readinput(a,nrowa,ncola);

printf("\n\nsecond table:\n");
readinput(b,nrowb,ncolb);

computemultiply(a,b,c,nrowa,ncola,nrowb,ncolb);
printf("\n\nSums of the elements:\n\n");
writeoutput(c,nrowa,ncolb);
}

/*read in a table of integers*/
void readinput(int a[][MAXCOLS],int m,int n)
{
int row, col;
for(row=0;row<m;++row)
printf("\nEnter data for row no. %2d\n",row+1);
for(col=0;col<n;++col)
scanf("%d",&a[row][col]);
}
return;
}

/*Multiply the matrices */
void computemultiply(int a[][MAXCOLS],int b[][MAXCOLS],int c[]
[MAXCOLS],int m,int n, int p)
{
int j,k,l;
for(j=0; j<m;++j)
for(k=0;k<p;++K)
{
c[j][k]=0;
for(l=0;l<n;++l)
c[j][k]=c[j][k]+a[j][l]*b[l][k];
}

void writeoutput(int a[][MAXCOLS],int m,int n)
{
int j,k;
for(j=0;j<m;++j)
for(k=0;k<n;++k)
printf("%4d\n",a[j][k];
}
return;
}

Dear friend,
There is nothing to be done much to convert this
program to java.
But u seem to be a very lazy person.
U seem to have no knowwledge of java.
Sorry friend, but read java and try it your self.
U will laugh upon yourself once u learn java !
