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.

A circuit contains three resistors connected in parallel. The value of R1 is 2 K , the value or R2 is 6 K , and the value of R3

mezya [45]

In a parallel connection, the voltage is same in every branch.
Now, three <span>three resistors connected in parallel.
R1 = 2k ohm
</span>R2 = 6k ohm
R3 = 10k ohm
in parallel, net resisitance = $\frac{ R_{1}R_{2}R_{3} }{R_{1}R_{2} + R_{2}R_{3} + R_{3}R_{1}}$

Now, putting the values, we get, R net = 1.30 k ohm.
Ans, voltage = 100 VDC
Thus, power = $\frac{ V^{2} }{R} = \frac{ 100^{2} }{1.3 k} \\ \\ where \\ k = 10^{3}$
= 7.69 Watt

amm1812

Answer:

The answer is "Option D".

Explanation:

OLAP reports stands for Online Analytical Processing reports, These reports provide a platform that behind many application use in Business Intelligence. and other options are incorrect that can be described as follows:

In option A, It is used to store the data into the OLAP report, that's why it is not correct.
In option B, It is software that is used for analytics data, that's why it is not correct.
In option C, It is used for finding index values in the 2D array that's why it is not correct.

What method of the String object searches the string for an occurence of the specified search string?

KATRIN_1 [288]

Answer:

the indexOf() method

Explanation:

The indexOf() method in java returns the first occurrence of the of the string or a character specified in it.It can be used to search both a character or a string.

for example:-

import java.util.*;

import java.lang.*;

import java.io.*;

class indexOf

{

public static void main (String[] args)

{

String s="IamNumber4";

int l=s.indexOf("Num");//using indexOf() method on string object..

System.out.println(l);

}

Output:-
