Rewrite each of the fragments using nested if statement

Question

Solve the following problems(a,b,c).

3. Rewrite each of the following fragments using nested if statements without compound conditions.

a. If (( rate = = 1) && (sum > 1000))
{
x = x + 1;
}
else if ((rate == 1 ) && (sum <= 1000))
{
x = x + 2;
}
else if ((rate == 2) && (sum > 1000))
{
x = x + 3;
}
else if ((rate ==2) && (sum <= 1000))
{
x = x + 5;
}

b. If (((a > 0) && (b > 0)) || (c > 0))
{
System.out.println(" Option one");
}
else
{
System.out.println("Option two");
}

c. If ((a > 0) && (b > 0))
{
System.out.println("Both Positive");
}
else
{
System.out.println ("Some Negative");
}
