*i need help with 3 different java programs*

1)/* ********************************************************   The program prompts for a value which will determine the   number of repetitions for the loop. Within the loop the   program will prompt for a number and add the value   value entered to an accumulator.******************************************************** */import java.util.Scanner;public class Lab0701 {

the while loop is controlled bythe length of the string */

        while(i < lineIn.length()) {          c = lineIn.charAt(i);          if(Character.isUpperCase(c))            count++;          i++;          }
        System.out.println("Count is: " + count);      }

import java.util.Scanner;public class Lab0704 {

public static void main(String[] args) {

int runTime   = 0;int totalTime = 0;double avg    = 0.0;int numTimes = 0;Scanner inp = new Scanner(System.in);
System.out.print(" Enter running time in seconds or -1 to end: ");runTime = inp.nextInt();while(runTime != -1){

totalTime += runTime;System.out.print(" Enter running time in seconds or -1 to

end: ");

runTime = inp.nextInt();

}

// insert code to report the total time, the number of times entered and theaverage time
      }

Explanation / Answer

java program1

import java.util.Scanner;

public class Lab0701 {
public static void main(String[] args) {
   int limit = 0;
   int counter = 0; int valu = 0;
   int sum = 0;   
   float avg = 0.0F;
   // Prompt for a repetition limit
   Scanner kBd = new Scanner(System.in);
   System.out.print("Sum from 0 to...? ");
   limit = kBd.nextInt();
   // Develop the loop to sum the values between one (1) and the limit entered bythe user//
   valu=limit;
   while(valu>=1) {
       sum+=valu;
       valu--;
       counter++;
   }
   System.out.println(" The sum of the numbers between 0 and " + limit + " is..." + sum);
   System.out.println(" The number of repetitions for the loop is..."+counter);
   System.out.println(" **** end of Lab0701 **** ");
   }
}

In progarm1 value of limit which is taken by user assigned to another variable valu

In while loop put condition valu>=1, so that it can sum upto 1 from input given by user.

And within loop write counter++, to count number of repetitions loop.

Java Program2

public class Lab0703 {

   public static void main(String[] args) {
       char c;int count = 0;
       int i = 0;
       String lineIn = "AranDomlINeoFiNPutToTeSt";   
       System.out.println("Input: " + lineIn);
       /* Note:
       the while loop is controlled bythe length of the string */
       while(i < lineIn.length()) {
           c = lineIn.charAt(i);
           if(Character.isUpperCase(c))   
               count++;   
           i++;   
          
       }
       System.out.println("Count is: " + count); }}

In progarm2, you did almost correct, but only 2 changes you have to do to run successfully,

First, remove one curley braces after i++; statement

Second Add one curley braces at end of program.

Java Progarm 3

import java.util.Scanner;
public class Lab0704 {
public static void main(String[] args) {
int runTime = 0;
int totalTime = 0;
double avg = 0.0;
int numTimes = 0;
Scanner inp = new Scanner(System.in);
System.out.print(" Enter running time in seconds or -1 to end: ");
runTime = inp.nextInt();
while(runTime != -1){
   numTimes++;
totalTime += runTime;
System.out.print(" Enter running time in seconds or -1 toend: ");
runTime = inp.nextInt();
}

// insert code to report the total time, the number of times entered and theaverage time
avg=(float)totalTime/numTimes;
System.out.println("The Total time is..."+totalTime);
System.out.println("The number of times entered by user is..."+numTimes);
System.out.println("The Average time is...:"+avg);

}
}

In program 3 add one statement within while loop i.e. numTimes++; to count the numbered of times entered by user

And after while loop add statement avg=(float)totalTime/numTimes;

to count average of times which is entered by user.
