Write a program to take a string as input and output its reverse.
The given code takes a string as input and converts it into a char array, which contains letters of the string as its elements.
Sample Input:
hello there
Sample Output:
ereht olleh
can any body tell how i can do this ?
try this code it will works
import java.util.Scanner;
public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
String text = scanner.nextLine();
char[] arr = text.toCharArray();
//your code goes here
for(int i = 0; i < arr.length; i++){
System.out.print(arr[arr.length - i - 1]);
}
}
}
import java.util.Scanner;
public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
String text = scanner.nextLine();
char[] arr = text.toCharArray();
char[] c;
//your code goes here
for(int i=arr.length;i>-1;i--)
System.out.print(c[i])
}
change char[] c to a String and construct it in the loop.
String str = "";
for(int i = arr.length-1; i >= 0; i--){
str = str + arr[i];
}
System.out.println(str) ;
// first, you should initialize your 'c' char array:
char[] c = new char[arr.length];
// then you should acess array items by giving index in square brackets (so, you doesn't need to iterate backwards:'):
for (int i=0; i<arr.length; ++i)
c[i] = arr[arr.length-i-1];
// also in second loop:
System.out.print(c[i]);
import java.util.Scanner;
public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
String text = scanner.nextLine();
char[] arr = text.toCharArray();
for(int i=arr.length-1;i>=0;i--)
{
System.out.println(arr[i]);
}// Just we start printing from back side
}
}
import java.util.Scanner;
public class Program
{
public static void main(String[] args) {
//code by jeho
Scanner scanner = new Scanner(System.in);
String text = scanner.nextLine();
char[] arr = text.toCharArray();
for(int i=arr.length-1;i>=0;i--)
{
System.out.println(arr[i]);
}
}
}
Try this on Inteliji
public static void main(String[] args) {
Scanner text = new Scanner(System.in);
String input;
System.out.println("Enter the your value in letter");
input =text.nextLine();
char[] output = input.toCharArray();
for (int i = output.length -1; i>=0; i--) {
System.out.println(output[i]);
}
import java.util.Scanner;
public class Program
{
public static void main(String[] args) {
Scanner scanner = new Scanner(System.in);
String text = scanner.nextLine();
char[] arr = text.toCharArray();
for(int i=arr.length-1;i>=0;i--)
{
System.out.println(arr[i]);
}// easy does it
}
}
