How can a staircase with n steps be implemented in Java?
A staircase with n steps can be implemented in Java using a loop to print the steps. Here is an example code snippet: java public class Staircase public static void main(String args) int n 5; // number of steps for (int i 1; i n; i) for (int j 1; j i; j) System.out.print(""); System.out.println(); This code will print a staircase with 5 steps using "" symbols. You can adjust the value of n to change the number of steps in the staircase.

What is a class declaration?
A class declaration tells the compiler what your class will be called, what data it will contain, and what methods it will have. For example, in Java and C# it looks roughly like this: class MyClass { private int x; private int y; public MyClass(int px, int py) { x = px; y = py; } public int sumXY() { return x + y; } } This declares a class called 'MyClass' with two data elements (or variables), called 'x' and 'y'. They are integers (whole numbers). The class has a constructor method (constructor methods always have the same name as the class, so the constructor method is also called 'MyClass'). You give two numbers to the constructor method, and it fills in the two numbers in the MyClass object with those two numbers. The class also has another method, called 'sumXY', which returns the sum of the two numbers the object contains. The 'public' and 'private' are used to determine who can or can't see the variables and methods of your class. If a variable or method is marked 'private', it can only be seen by methods inside the class. If it's marked 'public', other classes can reach inside and look at it or even change it. Hope this helps.
What is an InetAddress?
It is a class in Java which represents an Internet Protocol (IP) address. An instance of an InetAddress consists of an IP address and possibly corresponding hostname. The Class represents an Internet address as Two fields: 1- Host name(The String)=Contain the name of the Host. 2- Address(an int)= The 32 bit IP address. This fields are not public, so we cant Access them directly. There is not public constructor in InetAddress class, but it has 3 static methods that returns suitably initialized InetAddress Objects. public String getHostName() public byte[] getAddress() public String getHostAddress()
Syntax of printf?
I think you can use 'printf' like blew, int printf( const char *format [, argument]... );int _printf_l( const char *format, locale_t locale [, argument]... );int wprintf( const wchar_t *format [, argument]... );int _wprintf_l( const wchar_t *format, locale_t locale [, argument]... );at the same time, I give a example using the 'printf',/** * example using the 'printf' */include int main() { int e; int i; e = _set_printf_count_output( 1 ); printf( "%%n support was %sabled.\n", e ? "en" : "dis" ); printf( "%%n support is now %sabled.\n", _get_printf_count_output() ? "en" : "dis" ); printf( "12345%n6789\n", &i ); // %n format should set i to 5 printf( "i = %d\n", i ); }
Was public schools int he south segregared?
I'll assume that the question here is "Were public schools in the South segregated?" On that tack, yes. Up until the case of Brown vs. Board of Education in 1954, I believe.
Create a class rectangle The class has attributes length and width each of which is defaults to 1 It has member functions that calculates the perimeter and the area of the rectangle it has set?
