Create a program that will display all odd letters in uppercase and all even letters lowercase in the alphabet using a loop. I have done Arrays but my prof. requires me not to declare values
public class alpha{ public static void main (String[] args) {
u can use ascii values like as for ‘a’ it is 97 now we have to print “c” 100 in lower case so we simply subtract 32 from ‘c’ ascii value to get ‘C’ next is ‘f’ i.e 103 then 106 and so on. so logic could be like char[26] B; int[26] A; for(int i=0;i<26;i++) { A[i]=(i+97); } for(i=0;i<26;i++) { if(i%2==0||i==1) continue; else A[i]=A[i]-32; }
how to create a program of bubble sort which has names and marks of ten students in two arrays ‘names[] and marks[]’. You are required to sort these using ‘Bubble Sort’ algorithm. how to compare two neighboring objects, and to swap them if they are in the wrong order.
The program should display both the raw and sorted contents of these arrays. Follow the steps below to implement the desired solution
Steps to follow
1. The program is to take the sorting parameter as command line argument. So 1. If the command line argument is “names”, then the result should be sorted by names 2. If the command line argument is “marks”, then the result should be sorted by marks. In this case you should also display the student’s rank
how to write the program for Employee Information System using the following methods
An organization keeps pay scale data about each employee in its database. One of the purposes is to calculate income tax for each employee. Each Employee contains the following details:
Employee Class
Fields:
Employee ID (int)
Name (String)
basic, hra, da (int)
manager (Employee) – This field points to the manager for this employee. Each employee is assumed to report to only one manager.
Constructors:
Employee()
Employee(int id, String name)
Methods:
get/set methods
int calculateMonthlySalary()
int calculateYearlySalary()
int calculateIncomeTax()
String toString()
Manager Class
Inherit a class Manager from Employee. It has the following additional information
Fields:
totalReportees (int) – Number of people who are reporting to this supervisor. This number can be anywhere between 0 and 5, both inclusive.
Employee[] reportees – An array of Employee objects who report to this supervisor. Assume that each manager has a maximum of 5 direct reportees.
Constructors:
get/set methods
Manager ()
Manager (int id, String name)
Methods:
void addReportee(Employee)
print() – To display the details of the manager
print(level) – Print the reportees starting from this manager in a tree fashion. Prefix a ‘*’ to the name of the manager, if he has employees reporting to him
Algorithms:
monthly salary = (basic + hra + da)
yearly salary = monthly salary * 12 if (salary less than 100000) no tax if salary between 100000 – 500000 tax is 20 % of amount above 100000 if salary above 500000 tax is 20 % of amount above 100000 and below 500000, and 40 % of amount above 500000
If this manager already has 5 reportees, print an error message and do not add the new reportee.
Remember that a Manager may have other managers as reportees, there by creating a tree-like employee reporting structure.
Following is an example of output of printTree() method of Manager Class:
If Paul and Henry report to Nick. John reports to Paul. Calvin and Smith report to Henry. Then the tree will look like:
*Nick
*Paul
John
*Henry
Calvin
Smith
The setManager() method should also add the current object as a reportee for the manager
print() – To display the details of the employee along with monthly and yearly salary
i am very new to this, can plz help me Write a program to take one command line argument.

what situations we are using While and do-while loop please tell me. Tell me one situation where we have to use while or do-while loop without that we cant run our program please tell me that type of situations
Thanks i greatly appriciate your site. It was down for a while last week. I was really upset. I am learning a lot from this site
Create a program that will display all odd letters in uppercase and all even letters lowercase in the alphabet using a loop. I have done Arrays but my prof. requires me not to declare values

{
if (i%2==0)
System.out.print (apl[i].toUpperCase());
else
System.out.print (apl[i]);
}
}
}
u can use ascii values
like as for ‘a’ it is 97 now we have to print “c” 100 in lower case so we simply subtract 32 from ‘c’ ascii value to get ‘C’ next is ‘f’
i.e 103 then 106 and so on.
so logic could be like
char[26] B;
int[26] A;
for(int i=0;i<26;i++)
{
A[i]=(i+97);
}
for(i=0;i<26;i++)
{
if(i%2==0||i==1)
continue;
else
A[i]=A[i]-32;
}
for(int i=0;i<26;i++)
{
B[i]=Character.ParseChar(A[i]);
}
for(int i=0;i<26;i++)
{
System.out.println(B[i]);
}
Hi this will help you what you need thank you
