Write a function named delete Letter that has 2 parameters. The first parameter is a string, the second parameter is an integer.

The function removes the character located at the position specified by the integer parameter from the string. For example, if the function is being called with the following statement: deleteLetter ("timetable", 3); the string will become "tietable", where the third character, 'm' has been removed.

Answer:

//import package

import java.util.*;

// class name

class Solution

{

// method to remove the character at given index

public  static void deleteLetter(String st,int in)

{

// remove the character at index in

 st=st.substring(0,in-1)+st.substring(in);

 System.out.println(st);

}

// main method of class

public static void main (String[] args) throws java.lang.Exception

{

   try{

//scanner object to read input

   Scanner scr=new Scanner(System.in);

// read string

   System.out.print("Enter the string:");

                    String st=scr.nextLine();

// read index

  System.out.print("Enter the index:");

  int in=scr.nextInt();

// call method

  deleteLetter(st,in);

   }catch(Exception ex){

       return;}

}

}

Explanation:

Read a string with the help of Scanner object.Then read the index of character to be remove.Call the method deleteLetter() with parameter string and index.It will make substring from 0 to "in-1" and "in" to last of the string.Then add both the string.This will be the required string.

Output:

Enter the string:timetable

Enter the index:3

tietable

Sonic the Hedgehog (1991)
e-lub [12.9K]

Answer:

What if we made a fast game?

Explanation:

The mascot is the person, animal or thing which brings good luck, just like Mario. However, this is not a problem with Sonic the Hedgehog. And the Hedgehog is powerful enough to cross any barrier. Hence tieing the collectibles is not required. And the Hedgehog is quite cute and domestic. But it moves only 10 meters per second if we are considering the maximum speed. Hence, the correct option is certainly what if we made a fast game? And this is option C.

What must you be careful of when retrieving messages/data from mobile devices in public?

We must be careful of when retrieving messages/data from mobile devices in public because of Bluebugging.    It is a form of attack through the use of Bluetooth.  It is more than just Bluesnarling and Bluejacking.  It goes beyond, allowing the thieves to take control of a device.

NemiM [27]

Answer:

Here is the Bank Account class:

public class Bank Account {   //class definition

   private String name;  //private String type field to hold name

   private double balance;    // private double type field to hold balance

    public Bank Account(String name, double balance) {  // parameter constructor that takes

//this keyword is used to refer to the data members name and balance and to avoid confusion between name, balance private member fields and constructor arguments name, balance

 this.name = name;  

 this.balance = balance;  }    

   public void deposit(double amount) {   //method to deposit amount

               balance = balance + amount;     }    // adds the amount to the account causing the current balance to increase

   public void withdraw(double amount) {  //method to withdraw amount

 balance = balance - amount;   }   //subtracts the amount causing the current balance to decrease

    public String toString() {  // to display the name and current balance

              return name + " , $" + balance; }  } //returns the name and the current balance separated by a comma and dollar

Which of the following would be a valid method call for the following method? public static void showProduct (int num1, double n
Alenkinab [10]

Answer:

showProduct(int,double)

for example: showProduct(10,10.5) is the correct answer even showProduct(10,10.0) is also correct but showProduct(10.0,10.5) or showProduct(10,10) or showProduct(10.0,10) are wrong calls.

Explanation:

The code is

  1.       <em>public static void showProduct (int num1, double num2){</em>
  2. <em>       int product;</em>
  3. <em>       product = num1*(int)num2;</em>
  4. <em>       System.out.println("The product is "+product);</em>
  5. <em>       }</em>

showProduct is function which asks for two arguments whenever it is called, first one is integer and second one is of type double which is nothing but decimal point numbers. Generally, in programming languages, 10 is treated as integer but 10.0 is treated as decimal point number, but in real life they are same.

If showProduct( 10,10.0) is called the output will be 'The product is 100'.

Strange fact is that, if you enter showProduct(10,10.5) the output will remain same as 'The product is 100'. This happens because in the 3rd line of code,which is <em>product=num1*(int)num2</em>, (int) is placed before num2 which makes num2 as of type integer, which means whatever the value of num2 two is given, numbers after decimal is erased and only the integer part is used there.

This is necessary in JAVA and many other programming languages as you <u>cannot</u><u> multiply two different datatypes</u> (here one is int and another is double). Either both of them should be of type int or both should be of type double.
