Answer:
class Main {
static void printPowers(int howMany, int nrRows) {
for(int n=1; n<=nrRows; n++) {
for(int power = 1; power<=howMany; power++) {
System.out.printf("%d ", (int) Math.pow(n, power));
}
System.out.println();
}
}
public static void main(String[] args) {
printPowers(3, 5);
}
}
class Main {
static void printPowers(int howMany, int nrRows) {
int n = 1;
do {
int power = 1;
do {
System.out.printf("%d ", (int) Math.pow(n, power));
power++;
} while (power <= howMany);
System.out.println();
n++;
} while (n <= nrRows);
}
public static void main(String[] args) {
printPowers(3, 5);
}
}
Explanation:
The for loop gives the cleanest, shortest code.

Answer:
I think it is the first one
Explanation:
<span>public void myMethod(int w, int y, int z) {
</span>int a, b, c, d, e, f, g, h, i, j, k, l;
<span>a = w * z;
</span>b = w * z + y;
c = w * -z;
d = w * --z + y++;
e = w * z-- + ++y<span> ;
</span>f = w + z * y;
g = w – y + z;
h = (w + y) * z;
i = y / w;
j = y / z;
k = w % y;
<span>l = y % w;
</span>System.out.println( "%d %d %d %d %d %d %d %d %d %d %d %d", a,b,c,d,e,f,g,h,i,j,k);
}
To use
myMethod(2, 7, 12);
Disk access is way slower than
memory access. Caching is a technique to improve the disk access time. Block cache is a caching technique which
reduces disk accesses time. Here a
portion of disk is bought to cache for reading and a modified blocks are first
changed in cache but reflected in the disk at one go. On the other hand with write through caching
each modified block is written to cache and at the same time it is written to
the disk. Write- through caching
requires more disk I/O so they can have a negative effect on the performance.
