What is the wrong in the pragram

Question

Answer 1

Sidharth Patnaik

Still xyz declared 2 times.

Check my shared code

Answer 2

Sidharth Patnaik

Many mistakes

1 - main method missing

2 - String not string in get method

3 - declaration of 'i' in for loop is missing

4 - else can't have condition so there should be

else if()

5 - semicolon (;) should not be after if condition because it would stop execution and inside if block code will not execute.

6 - declaration of 'z' is missing

7 - class name should start from Capital letter "Xyz"

Basically you need to learn how to use syntax properly.

Answer 3

Sidharth Patnaik

No still not right

As I told in first reply learn how to use syntax properly

1 - make variables private

2 - In main method there should be (String[] args)

3 - You have created same class 2 times

4 - print inside get method

5 - Class object should be like:

xyz obj = new xyz(); //you have written obj()

6 - you have 1 method get which accept 1 argument, so obj.get(); not make sense

here is right solution:

Answer 4

Your 1st "else" would need to be an "else if".

edit:
* you deleted the main method and never called getX() – you need to pass a string to getX()
* you missed to declare variables like i or z
* your conditions fails, as you confused AND and OR: an integer cannot be greater than 65 and smaller than 90 at the same time
* CharAt() returns an character – you need to convert it to an integer
* if you specify a condition, you cannot use an else, you need if or else if, respectively

Answer 5

Sidharth Patnaik

Yes but print inside method so you can get output

Answer 6

Sidharth Patnaik

Print these lines inside get method:

System .out.println ("total number of capital="+toup);
System .out.println ("total number of small="+tolow);
System .out.println ("total number of space="+space);

And change second class xyz (which has main method) with other name like Abc

Answer 7

Try to do again by following suggestion posted above ones and reply with update code. If you don't understand anything then you can ask about that specific doubt.. Giving only code will not help you... hope you understand it.

Answer 8

Where is main method? To run it, you must need main method.
Add main method and call this method from main method...

edit : Sidharth Patnaik

see this , revise the lessons after:

class xyz {

//this is method, execution starts from here
public static void main(String []arg) {
get("AbcdE"); // calling the method

}

public static void get(String x) {
int toup=0, tolow=0, space =0; // add in method otherwise you need an object to use those or make static variables

for(int i=0;i<x.length();i++)
{
char z=x.charAt(i);
if (z>=65 && z<=90)
{
toup++;
}
else if(z>=97 && z<=120)
{
tolow++;
}
else
{
space++;
}
}

System.out.println ("total number of capital = "+toup);
System.out.println ("total number of small = "+tolow);

}
}

Answer 9

class xyz
{
int toup=0;
int tolow=0;
int space =0;
void get(String x)
{
for (int i=0;i<x.length();i++)
{
char z=x.charAt(i);
if (z>=65 && z<=90)
{
toup++;
}
else if(z>=97 && z<=120)
{
tolow++;
}
else
{
space++;
}
}
}
System .out.println ("total number of capital="+toup);
System .out.println ("total number of small="+tolow);
System .out.println ("total number of space="+space);

}
public class xyz
{
public static void main(String[] args)
{
xyz obj=new xyz();
obj.get("Sidharth Patnaik");

}
}

Answer 10

Yeah now its done❤

Answer 11

Can u solve my answer please

Answer 12

class xyz
{
int toup=0;
int tolow=0;
int space =0;
void get(String x)
{
for (int i=0;i<x.length();i++)
{
char z=x.charAt(i);
if (z>=65 && z<=90)
{
toup++;
}
else if(z>=97 && z<=120)
{
tolow++;
}
else
{
space++;
}
}
System .out.println ("total number of capital="+toup);
System .out.println ("total number of small="+tolow);

}
}

Answer 13

It showing no output

Answer 14

Thank you sir,now i understood

Answer 15

The open site chefra

Answer 16

class xyz
{
int toup=0;
int tolow=0;
int space =0;
void get(String x)
{
for (int i=0;i<x.length();i++)
{
char z=x.charAt(i);
if (z>=65 && z<=90)
{
toup++;
}
else if(z>=97 && z<=120)
{
tolow++;
}
else
{
space++;
}
}
}
System .out.println ("total number of capital="+toup);
System .out.println ("total number of small="+tolow);
System .out.println ("total number of space="+space);

}
public class xyz
{
public static void main(String args)
{
xyz obj=new obj();
obj.get("Sidharth Patnaik");
obj.get();
}
}

Answer 17

Is it correct now??

Answer 18

//corrected code.
// read comments, for changes made

class xyz
{
int toup=0;
int tolow=0;
int space =0;

void get(String x)
{
for (int i=0;i<x.length();i++)
{
char z=x.charAt(i);
if (z>=65 && z<=90)
toup++;

else if(z>=97 && z<=120)
tolow++;

else{
space++;
}
}
System .out.println ("total number of capital = "+toup);
System .out.println ("total number of small = "+tolow);
System .out.println ("total number of space = "+space);
}
} //add this to end of class xyz

class Main //class name must be different in same file
{
public static void main(String args[]) // Argument must br string of array, not srring.
{
xyz obj=new xyz(); // creating object of xyz() , its not obj()
obj.get("Sidharth Patnaik");
//obj.get(); you dont have get() method without parameter
}
}

Answer 19

Now is it correct

Answer 20

If i change it showing error
