Question

Give answer according to fill in the blanks.

1.Define a class called Fraction . This class is used to represent a ratio of two integers.Include mutator methods that allow the user to set the numerator and the denominator. Also include a method that returns the value of numerator divided by denominator as a double . Include an additional method that outputs the value of the fraction reduced to lowest terms (e.g., instead of outputting 20/60, the method should output 1/3). This will require finding the greatest common divisor for the numerator and denominator, then dividing both by that number. Embed your class in a test program.

public class Fraction {

   private int num1;

   private int num2;

   public void _____(1)_________{

               this.num1 = num1;

   }

   public void setNum2(___(2)______){

               this.num2 = num2;

   }

   //method two number divided,return double data

   public double div(){

               return (___________(3)_______________);

   }

   public String getFraction(){

               int tmp1,tmp2;

               tmp1 = this.num1;

               tmp2 = this.num2;

       //set remain from two number divided

               int remain = _______(4)_____________;

      //do loop,util the remain is 0 .then the common divisor is tmp2

               _____(5)__________{

                           tmp1 = tmp2;

                           tmp2 = remain;

                           remain = ______(6)__________

               }

      //get the result of num1 divide common divisor

               int a =_________(7)___________;

      //get the result of num2 divide common divisor.

               int b = ________(8)________;

               return a+"/"+b;

   }

   public static void main(____(9)______) {

               //get num from keyboard

       Scanner scan = ______(10)_________;

       int num1,num2;

       double dividResult =0;

       String fractionResult =””;

       num1=num2=0;

       num1 =_____(11)_______;

       num2 = _____(12)__________;

       Fraction fr =_______(13)____________;

       Fr.setNum1(num1);

       Fr.setNum2(num2);

       dividResult =______(14)_______;

       fractionResult =______(15)________;

       System.out.println(fractionResult);

   }

}

2.

Get the size from console and create an int array with that size, then assign a random value between [1,10] to each element of the array,finally output the array in 6 elements per line.

public static void main(____1____){

        //declared the int array whith size 10

        ____2____ arr1 = new ____3____;

        // use for loop ,set value to each element

        for(____4____){

           ____5____ = (____6____)(Math.random()*10);

        }

        //output the element of array , 6 element one line

        for(____7____){

            if(____8____){

                ____9____;

            }else{

                System.out.print(____10____);

            }

        }

    }

Answer 1

Dear Student ,

As per the requirement submitted above , kindly find the below solution.

Question 2:

Here a new java program with name "Main.java" is created, which contains following code.

Main.java :

public class Main //Java Class
{ //Main method
   public static void main(String[] args) {
//declared the int array with size 10
int[] arr1 = new int[10];
// use for loop ,set value to each element
for(int i=0;i<10;i++){
arr1[i] = (int)(Math.random()*10);

}
//output the element of array , 6 element one line
for(int i=0;i<10;i++){
if(i==6){
System.out.println();//used for new line
System.out.print(arr1[i]+" ");
}else{

System.out.print(arr1[i]+" ");

}

}

}
}
