programming homework

can someone help me put these codes into a program? I missed a couple of classes and I don't know where to begin, if someone could start me off.

1. for (int count = 0; count < nums.length; count++)
nums[count] = INITIAL;
2.for (int count = names.length - 1; count >= 0; count--)
System.out.println(names[count]);

3.for (int index = 0; index < flags.length; index++)
flags[index] = (index%2 == 0);
4.public static float sumArray (float[] nums)
{
float sum = 0;
for (int count = 0; count < nums.length; count++)
sum += nums[count];
return sum;
}
:confused:
