Answer:
import java.util.Scanner;
public class num2 {
public static void main(String[] args) {
Scanner in = new Scanner(System.in);
int count =0;
int total = 0;
System.out.println("Enter the numbers");
int num = in.nextInt();
while(num!=-1){
total = total+num;
count++;
System.out.println("Enter the next number");
num = in.nextInt();
}
//Compute the average
double average = (double) total/count;
//Outputs
System.out.println("Total count of numbers entered "+(count));
System.out.println("Sum of the numbers "+total);
System.out.printf("Average is %.2f ",average);
}
}
Explanation:
- Using java programming language
- Import scanner class to receive user input
- declare variables count and total and initialize to zero
- Prompt user to enter numbers
- Use a while statement with the condition while(num!=-1)
- Within the while body keep prompting user to enter a number, increase count and update total
- when -1 is entered the loop breaks and average is calculated
- Use printf() method to print average to 2 decimal places.
String oldSeq="1100000111";
String segment="11";
String newSeq=oldSeq.replaceFirst(segment, "");
Answer:
java: error
C: false
Explanation:
In Java the compiler understand that you are trying to compare an integer (15) with a boolean (10 > 5) this generate the next error:
error: bad operand types for binary operator
In C the compiler convert (15 > 10 > 5) in (15>10) > (10>5) which is equal to TRUE > TRUE, the compiler can also read it as 1 > 1 (since 1 is TRUE and 0 is FALSE). like 1>1 is false then C program return false.
