What method of the Math object can be used to return the largest value from the values that are passed to it?

miss Akunina [59]

Answer:

the Math.max() method

Explanation:

The java.lang.* package contains all the essential components needed for a JAVA program which involves numbers and all the operations done on the numericals.

The java.lang.math class contains all the methods needed to perform mathematical operations on numerical values.

All the methods in the question are discussed below with examples.

Math.max() method

java.lang.Math.max(double/ int/ float a, double/ int/ float b)

This method returns the highest value from among the parameters passed to it.

The syntax for the above is

Numbers can be integers, float and double or long. The return type is the same as the parameters.

Two values to be compared are passed as arguments and the higher value of them is returned.

This function also accepts negative integers as parameters.

Math.max(-9, -2);

Gives -2 as the output.

Math.max(0.34, 0.45)

Gives 0.45 as the output.

Math.ceil() method

java.lang.Math.ceil(double/ int/ float a)

This method returns the nearest greater whole number for the given number.

Integer parameter returns an integer number.

Math.ceil(7);

Gives 7 as the output.

Decimal number will return the nearest higher integer.

Math.ceil(8.7);

Gives 9.0 as the output.

Math.ceil(-0.34)

Gives -0 as the output.

Math.pow() method

java.lang.Math.pow(double/ float/ int a, double/ float/ int b)

The above method returns the result of a raise to the power of b.

The first parameter is the base while the second parameter forms the exponent.

Math.pow( 2.3, 4.5 );

This calculates (2.3)^4.5.

Gives 42.44‬ as the output.

Math.pow( 2, 3 );

This calculates the value of 2^3.

Gives 8 as the output.

Math.abs() method

java.lang.Math.abs(double a)

This method returns non-negative value of the numerical parameter passed to it. Absolute of a number does not changes its value but changes the sign of a negative number. It returns the positive or negation of the negative input number.

Math.abs(-0.1234)

Gives 0.1234 as the output.

Math.abs(12.34)

Gives 12.34 as the output.

These methods require java.lang.Math to be imported in the program.

(1) Prompt the user to enter a string of their choosing. Output the string.

barxatty [35]

Answer:

See solution below

See comments for explanations

Explanation:

import java.util.*;

class Main {

public static void main(String[] args) {

//PrompT the User to enter a String

System.out.println("Enter a sentence or phrase: ");

//Receiving the string entered with the Scanner Object

Scanner input = new Scanner (System.in);

String string_input = input.nextLine();

//Print out string entered by user

System.out.println("You entered: "+string_input);

//Call the first method (GetNumOfCharacters)

System.out.println("Number of characters: "+ GetNumOfCharacters(string_input));

//Call the second method (OutputWithoutWhitespace)

System.out.println("String with no whitespace: "+OutputWithoutWhitespace(string_input));

}

//Create the method GetNumOfCharacters

public static int GetNumOfCharacters (String word) {

//Variable to hold number of characters

int noOfCharactersCount = 0;

//Use a for loop to iterate the entire string

for(int i = 0; i< word.length(); i++){

//Increase th number of characters each time

noOfCharactersCount++;

}

return noOfCharactersCount;

}

//Creating the OutputWithoutWhitespace() method

//This method will remove all tabs and spaces from the original string

public static String OutputWithoutWhitespace(String word){

//Use the replaceAll all method of strings to replace all whitespaces

String stringWithoutWhiteSpace = word.replaceAll(" ","");

return stringWithoutWhiteSpace;

}
