Question

Please answer both questions thank you.

Question 52 (1 point) What is the output of the code snippet given below? String s = "abcde"; int i = 1; while (i < 5) { System.out.print(s.substring(i, i + 1)); i++;

Answer 1

Q1. OUTPUT: OF THE CODE..

import java.util.*;

import java.lang.*;

import java.io.*;

class Main

{

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

{

String s="abcde";

/*given the string here "abcde" since index starts from

0 to 4 to denote 5 Characters in the string we have....

and substring(k,l) prints the string from the given string from

string starting at index k and upto l-1.. as we have seen it..

so in each substring(i,i+1 ) will print substring from i to i i.each

1 Character the Character at index i so

in case of

1st iteration it will print s[1]=b

second iteration s[2]=c

third iteration s[3]=d

s[4]=e......so on..

and loop stops when i=5.. so

output: bcde

you can see it in the output section below...

*/

int i=1;

while(i<5)

{

System.out.print(s.substring(i,i+1));

i++;

}

}

}

OUTPUT;

bcde

SINCE SUBSTRING(I,I+1) STARTS AT INDEX I AND UPTO I+1-1 SO ONE CHARACTER AT A TIME OF GIVEN INDEX..

SO OUTPUT:

AS ABOVE..

Q2. WE PRINT THE ANSWER BELOW CODE.

import java.util.*;

import java.lang.*;

import java.io.*;

class Main

{

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

{

int count=0;

   

  /*since we have nested loops here in this code

so for the first for loop we have it running from i =0 to i=2 ..[0 1 2 ]

so it runs for 3 times .. %outer loop .

now for each outer loop we have an inner loop .. runiiing from j =1 to 3..[1,2, 3..]

so 3 times so we have the nested loop running over 3*3 times.

so 9 times

answer =9 since println function prints line each times ..

so we have counted also the output here below..

and count =9 .. you can well see in the output:

*/

    

for(int i=0; i<3; i++)

{

for(int j=1; j<4; j++)

{

System.out.println(""+ i+" "+j);

count++;

}

        

}

System.out.println("answer = "+count);

}

}

OUTPUT;

0 1

0 2

0 3

1 1

1 2

1 3

2 1

2 2

2 3

answer = 9

SO THE NO.. OF TIMES LINES WILL BE PRINTED IS =9..

NOTE: IN CASE OF ANY QUERY PLZ ASK IN COMENT
