How to know if java is installed on a server.

A file named 'input.txt' contains a list of words. Write a program that reads the content of the file one word at a time. Check

Margarita [4]

Answer:

// here is code in java.

import java.io.*;

import java.util.Scanner;

class Main{

// function to check a word is palindrome or not

private static boolean is_Palind(String str1)

{

// if length of String is 0 or 1

if(str1.length() == 0 || str1.length() == 1)

{

return true;

}

else

{

// recursively check the word is palindrome or not

if(str1.charAt(0) == str1.charAt(str1.length()-1))

{

return is_Palind(str1.substring(1,str1.length()-1));

}

else

{

return false;

}

// driver function

public static void main(String[] args)

{// variable to store word

String word;

// BufferedWriter object

BufferedWriter buff_w = null;

// FileWriter object

FileWriter file_w = null;

// Scanner object

Scanner sc = null;

try

{

// read the input file name

sc = new Scanner(new File("input.txt"));

// output file

file_w = new FileWriter("output.txt");

// create a buffer in output file

buff_w = new BufferedWriter(file_w);

// read each word of input file

while(sc.hasNext())

{

word = sc.next();

// check word is palindrome or not

if(is_Palind(word))

{

// if word is palindrome then write it in the output file

buff_w.write(word);

buff_w.write("\n");

}

// close the buffer

buff_w.close();

// close the input file

sc.close();

}

// if there is any file missing

catch (FileNotFoundException e) {

System.out.println("not able to read file:");

}

// catch other Exception

catch (IOException e) {

e.printStackTrace();

}

Explanation:

Create a scanner class object to read the word from "input.txt" file.Read a word from input file and check if it is palindrome or not with the help of is_Palind() function.it will recursively check whether string is palindrome or not. If it is palindrome then it will written in the output.txt file with the help of BufferedWriter object. This will continue for all the word of input file.

Input.txt

Write the following function without using the C++ string class or any functions in the standard library, including strlen(). Yo

dolphi86 [110]

Answer:

The function in C++ is as follows

int chkInd(string str1, string str2){

int lenstr1=0;

while(str1[lenstr1] != '\0'){ lenstr1++; }

int index = 0; int retIndex=0;

for(int i=lenstr1-1;i>=0; i--){

while (str2[index] != '\0'){

if (str1[i] == str2[index]){

retIndex=1;

break; }

else{ retIndex=0; }

index++; }

if (retIndex == 0){ return i; }else{return -1;}}

}

Explanation:

This defines the function

int chkInd(string str1, string str2){

First, the length of str1 is initialized to 0

int lenstr1=0;

The following loop then calculates the length of str1

while(str1[lenstr1] != '\0'){ lenstr1++; }

This initializes the current index and the returned index to 0

int index = 0; int retIndex=0;

This iterates through str1

for(int i=lenstr1-1;i>=0; i--){

This loop is repeated while there are characters in str2

while (str2[index] != '\0'){

If current element of str2 and str1 are the same

if (str1[i] == str2[index]){

Set the returned index to 1

retIndex=1;

Then exit the loop

break; }

If otherwise, set the returned index to 0

else{ retIndex=0; }

Increase index by 1

index++; }

This returns the calculated returned index; if no matching is found, it returns -1

if (retIndex == 0){ return i; }else{return -1;}}

}

Create a Visual Logic flow chart with four methods. Main method will create an array of 5 elements, then it will call a read met

pogonyaev

Answer:

See explaination

Explanation:

import java.util.Scanner;

public class SortArray {

public static void main(String[] args) {

// TODO Auto-generated method stub

Scanner sc = new Scanner(System.in);

System.out.println("Enter Size Of Array");

int size = sc.nextInt();

int[] arr = new int[size]; // creating array of size

read(arr); // calling read method

sort(arr); // calling sort method

print(arr); // calling print method

}

// method for read array

private static void read(int[] arr) {

Scanner sc = new Scanner(System.in);

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

System.out.println("Enter " + i + "th Position Element");

// read one by one element from console and store in array

arr[i] = sc.nextInt();

}

// method for sort array

private static void sort(int[] arr) {

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

for (int j = 0; j < arr.length; j++) {

if (arr[i] < arr[j]) {

// Comparing one element with other if first element is greater than second then

// swap then each other place

int temp = arr[j];

arr[j] = arr[i];

arr[i] = temp;

}

// method for display array

private static void print(int[] arr) {

System.out.print("Your Array are: ");

// display element one by one

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

System.out.print(arr[i] + ",");

}
