Please help me transform this C++ code to java code....

Question

guys...please help me transform this C++ code to java code....please try to explain the code..thanks
[program]
#include <stdio.h>
#define ALIVE 1
#define DEAD 0
#define SZ 33
int stschk (int ,int );
main()
int s[SZ][SZ], i, j;
for (i=0; i<sz; i++ ) s[0] = DEAD;
for (j=0; j<sz; j++ ) s[0][j] = DEAD;
s[0][1] = ALIVE;
for (i=0; i<sz-1; i++) {
for ( j=1;j<sz;j++ ) {
s[i][j] = stschk(s[i][j-1],s[i+1][j];
if(s[i][j-1]==ALIVE) printf("*");
else printf(" ");
printf("\n");
int stschk(int s1,int s2)
if(((s1==DEAD)&&(s2==ALIVE))||
((s1==ALIVE)&&(s2==DEAD))) return ALIVE;
else return DEAD;

Being picky, that's not C++, that's C. Standard headers in C++ dont' have .h after them, loop variables are scoped with the for, you use constants rather than #defines, etc..
C and C++ both don't initialise arrays by default; you'd have to write an initialiser to get it to zero out the array:
    int s[sz][sz] = {};gcc will insert a call to memset to zero the array.
If the author was assuming that the array was zeroed out, there would be no point zeroing the first row and column.
The code reads values which haven't been initialised. If you mark such values explicitly undefined, and change the program to report an error when undefined, then you get several cases where the program makes such report.
So either it' s a primitive random number generator (some random number generators use uninitialised memory as a source of randomness), or it's buggy, or it's processing undefined data and throwing away the result. Either way, it cannot be directly be ported to Java if the undefined values (which are limited to a small area of the ouput) are significant.
