Answer:

new BigInteger(s);

See the explanation

Explanation:

Since "parseInt" throws a 'NumberFormatException"; the best solution will be to use 'BigInteger'. Since 's' is already assigned a value, we can print it out as:

System.out.println(new BigInteger(s));

The BigInteger class might need to be imported to the class using:

import java.math.BigInteger;

What processes can move a solute against its concentration gradient?
Rudiy27

Explanation:

To move substances against a concentration or electrochemical gradient, the cell must utilize energy in the form of ATP during active transport. Primary active transport, which is directly dependent on ATP, moves ions across a membrane and creates a difference in charge across that membrane.

Write a function that receives two numbers, m and n and calculates and displays the sum of the integers from m to n. For example
Evgesh-ka [11]

Answer:

The program to this question as follows:

Program:

//header file

#include <stdio.h> //defining header file

void inc(int m,int n) //defining method inc

{

   int sum, i; //declaring variable

   sum=m; //holding value of m variable

   for(i=++m;i<=n;i++) //loop for calculate number between given range  

   {

   sum=sum+i; //adding value

   }

   printf("sum of the integer is : %d",sum);//print value

}

int main() //defining method

{

   int m,n; //defining integer variable

   printf("Enter m value: "); //message

   scanf("%d",&m); //input value by user in variable

   printf("Enter n value: "); //message

   scanf("%d",&n);//input value by user in variable

   inc(m,n); //calling method

   return 0;

}

Output:

Enter m value: 3

Enter n value: 7

sum of the integer is :25

Explanation:

In the above code, an "inc" function is declared, that accepts integer parameters that are "m and n", inside the method two integer variable "sum and i" is declared, which is used in the loop.

  • The loop uses the user parameter to count value and uses the sum variable to calculate there sum.
  • In the main method, two integer variable n and m are declared, which take value from the user end, and at the last, we call the inc method, that prints sum value.

Write code statements that prompt for and read a double value from the user, and then print the result of raising that value to
andriy [413]

Answer:

Following are the code in Java Language:

Scanner sc = new Scanner(System.in); // create a instance of scanner class

DecimalFormat frmt = new DecimalFormat("0.###"); // create a instance of                // DecimalFormat class

System.out.println ("Enter the value: ");

double number = scan.nextDouble(); // Read the value by thje user

System.out.println (fmmt.format(Math.pow(number, 4))); // display the value

Explanation:

Following are the description of the code

  • Create an instance scanner class i.e "sc".
  • Create an instance of DecimalFormat class i.e "frmt".
  • Read the value by the user in the "number" variable of type double by using the nextDouble()method.
  • Finally, display the value by using System.out.println method. In this, we call the method format. The Math.pow() function is used to calculating the power up to the fourth value.
