Answer:

Following are the program in java language that is mention below

Explanation:

import java.util.*;  // import package

public class Half_XmasTree // main class

{

public static void main(String args[])  // main method

{

int k,i1,j1; // variable declaration  

Scanner sc2=new Scanner(System.in);   // create the object of scanner

System.out.println("Enter the Number of rows : ");

k=sc2.nextInt(); // Read input by user

for(i1=0;i1<k;i1++)  //iterating the loop

{

for(j1=0;j1<i1;j1++)  // iterating the loop

System.out.print(" ");

for(int r=k-i1;r>0;r--)  //iterating loop

System.out.print("*");  // print *

System.out.println();

}

}

}

Output:

Following are the attachment of output

Following are the description of program

  • Declared a variable k,i1,j1 as integer type .
  • Create a instance of scanner class "sc2" for taking the input of the rows.
  • Read the input of row in the variable "K" by using nextInt() method .
  • We used three for loop for implement this program .
  • In the last loop we print the * by using system.println() method.

Suppose that you are asked to modify the Stack class to add a new operation max() that returns the current maximum of the stack
Advocard [28]

Answer:

Following are the code to the given points:

Explanation:

For point 8.1:

public String max()//defining a method max

{

   String maxVal=null;//defining a string variable that holds a value

   for(int x=0;x<n;x++)

   {

       if(maxVal==null || a[i].compareTo(maxVal)>0)//defining if blok to comare the value

       {

           maxVal=a[i];//holding value in maxVal variable

       }

   }

   return maxVal;//return maxVal variable value

}

For point 8.2:

public void push(String item)//defining a method push that accepts item value in a parameter

{

       a[n]=item;//defining an array to hold item value

       if(n==0 || item.compareTo(maxVals[n-1])>0)//use if to comare item value

       {

               maxVals[n]=item;//holding item value in maxVals variable

       }

       else

       {

               maxVals[n]=maxVals[n-1];//decreasing the maxVals value

       }

       n++;//incrementing n value

}

public String pop()//defining a method pop

{

       return a[--n];//use return value

}

public String max()//defining a method max

{

       return maxVals[n-1];//return max value

}

  • In the first point, the max method is declared that compares the string and returns its max value.
  • In the second point, the push, pop, and max method are declared that works with their respective names like insert, remove and find max and after that, they return its value.

What technology gets its name from the notion that it ignores the traditional A, B, and C class designations for IP addresses?
goblinko [34]

Answer:

Classless Inter-Domain Routing

Explanation:

Classless Inter-Domain Routing (CIDR), pronounced “cider” or “sidder,” gets its name from the notion that it ignores the traditional A, B, and C class designations for IPv4 addresses and sets the network-host ID boundary wherever it wants to, in a way that simplifies routing across the resulting IP address spaces.
