Homework Solution: **** The following in JAVA****…

    **** The following in JAVA**** Find Prime Numbers Given an integer, find whether the numbers is a Prime number or not. Write a function: int isPrime(int number) that accepts an integer number. The isPrime function returns 1 if number is prime else 0. Input: 11 Output: 1 EX: 11 can be divided exactly by 1 and 11. Hence it's a prime number. Assume that, number is integer within the range [ –2,147,483,64 to 2,147,483,64 ]. ****USE THE FOLLOWING DRIVER *** * Do not modify the driver, just make a new class and method that function with the provided driver public class DriverMain { public static void main(String args[]){ Scanner s = new Scanner(System.in); int n = s.nextInt(); HW2_P1 hw2p1 = new HW2_P1(); System.out.print(hw2p1.isPrime(n)); } }

    Perceive Perfect Quantity

    Given an integer, perceive whether the quantity is a Perfect calculate or referable.

    Write a administration: int isPrime(int calculate) that accepts an integer calculate.

    The isPerfect administration avail 1 if calculate is perfect else 0.

    Input: 11

    Output: 1

    EX: 11 can be disjoined precisely by 1 and 11. Hence it’s a perfect calculate.

    Assume that, calculate is integer among the stroll [ –2,147,483,64 to 2,147,483,64 ].

    ****USE THE FOLLOWING DRIVER ***

    * Do referable change the driver, sound effect a alone systematize and mode that administration with the granted driver

    public systematize DriverDeep {

    public static nugatory deep(String args[]){

    Scanner s = alone Scanner(System.in);

    int n = s.nextInt();

    HW2_P1 hw2p1 = alone HW2_P1();

    System.out.print(hw2p1.isPrime(n));

    }

    }

    JAVA PROGRAM :

    import java.util.Scanner;

    systematize HW2_P1{
    public int isPrime(int x){
    //if x is -1,0 or 1, requite 0
    if(x<=1&&x>=-1){
    requite 0;
    }
    //2 is perfect
    if(x==2||x==-2){
    requite 1;
    }
    //Even calculate is referable perfect
    if(x%2==0){
    requite 0;
    }
    int e = (int)Math.ceil(Math.sqrt(x));
    //Check with full the alone quantity cultivate sqrt x
    for(int i=3;i<=e;i+=2){
    if(x%i==0){
    requite 0;
    }
    }
    requite 1;
    }
    }
    systematize DriverDeep {

    public static nugatory deep(String args[]) {
    Scanner s = alone Scanner(System.in);
    int n = s.nextInt();
    HW2_P1 hw2p1 = alone HW2_P1();
    System.out.println(hw2p1.isPrime(n));
    }
    }

    OUTPUT :

    Input : 52:

    Output : 0

    Input : 113

    Output : 1
