Design a class to overload a function series( ) as follows:
(a) void series (int x, int n) – To display the sum of the series given below:
x1 + x2 + x3 + ………. xn terms
(b) void series (int p) – To display the following series:
0, 7, 26, 63 ………. p terms
(c) void series () – To display the sum of the series given below:
1/2 + 1/3 + 1/4 + ………. 1/10

public class KboatOverloadSeries
{
void series(int x, int n) {
long sum = 0;
for (int i = 1; i <= n; i++) {
sum += Math.pow(x, i);
}
System.out.println("Sum = " + sum);
}
void series(int p) {
for (int i = 1; i <= p; i++) {
int term = (int)(Math.pow(i, 3) - 1);
System.out.print(term + " ");
}
System.out.println();
}
void series() {
double sum = 0.0;
for (int i = 2; i <= 10; i++) {
sum += 1.0 / i;
}
System.out.println("Sum = " + sum);
}
}Output

Invoking a method by passing the objects of a class is termed as:
- Call by reference
- Call by value
- Call by method
- Call by constructor
Define a class to overload the method perform as follows:
double perform (double r, double h) — to calculate and return the value of curved surface area of cone
void perform (int r, int c) — Use NESTED FOR LOOP to generate the following format
r = 4, c = 5
output
1 2 3 4 5
1 2 3 4 5
1 2 3 4 5
1 2 3 4 5void perform (int m, int n, char ch) — to print the quotient of the division of m and n if ch is Q else print the remainder of the division of m and n if ch is R
Consider the following program segment and answer the questions below:
class calculate { int a; double b; calculate() { a=0; b=0.0; } calculate(int x, double y) { a=x; b=y; } void sum() { System.out.println(a*b); }}Name the type of constructors used in the above program segment?
