Java Help Needed

Question

public class Program
{
public static void main(String[] args)
{
String str = "sololearn";
for(int k=0;k<str.length();k++)
{
if(k%2==0)
System.out.print(str[k]);
else
System.out.print("+");
}
}
}
why this program is not running?

Answer 1

@Ajay You can use str.charAt() and there are many more available:D

Answer 2

@Ajay Yes, it outputs places....I never knew you wanted characters:)

Answer 3

public class Program
{
public static void main(String[] args)
{
String str = "sololearn";
for(int k=0;k<str.length();k++)
{
if(k%2==0)
System.out.print(String.valueOf(k));
else
System.out.print("+");
}
}
}
Hope this helps! 😊

Answer 4

@Dayve
is their any alternative available for this problem? just for first print line.

Answer 5

@Dayve String.valueOf(k) is printing places of k, not characters.

Answer 6

@Dayve
sorry, I forgot to tell that. 😁

Answer 7

Thanks guys, this looks something appropriate for me.☺

Answer 8

@Nivedita Vaidya
if I declare String str="sololearn";
then why it's not working?

Answer 9

Replace str[k] with str.charAt(k)

Answer 10

This is another way to get your answer
public class Program
{
public static void main(String[] args)
{
String str[] = {"s","o","l","o","l","e","a","r","n"};

for(int k=0;k<str.length;k++)
{
if(k%2==0)
System.out.print(str[k]);
else
System.out.print("+");
}
}
}

Answer 11

str is a string variable and you are accessing it as an array as str[k] hence it is not working.
