Question1: Please fix all the errors in the code below

public class Homework1 {

            public static void main(String[] args) {

                        int  i1 = 10;           // line1

                        double   d1 = 5.0;          // line2

                        float  f1 = 2.05;          // line3

                        char   c1 =  i1;          // line4

                        short   s1 = c1;          // line5

                        float  f2 = d1 / f1;          // line6

                        double d2 = f1 + i1 + c1;          // line7

                        float  f3 = d1 - i1;          // line8

                        byte b1 = 3;          // line9

                        byte b2 = 4;          // line10

                        byte b3 = 2 * b1 - b2;          // line11

            }

}

 

 

Question2: (25 points)            Calculate the value of d1 and d2:

            int i = 15;

            int j = 10;

            float f1 = 2;

            float d1 =  i / j;

            float d2 =  i / f1;

d1 =

d2 =

 

Question 3:

What is the value of a, b, i, j after the statements below are excuted.

int a = 10; 

int b = 5; 

int i =  ++a

int j = b--; 

a =

b =

i =

j=

 

Question 4:

What's the difference between continue and break?

 

 

 

 

Question 5:  

public class Example {

            public static void main(String[] args) {

                        int i = 1;

                        while (i <= 10) {

                                    i = i + 2;

                                    System.out.print(i + "  ");

                        }                     

            }

}

Output:

 

Question 6:  

public class Example {

            public static void main(String[] args) {

                        for (int k = 20; k >=10; k = k -3)  {

                        System.out.print(k + "  ");

                        }

            }

}

Output:

 

Question 7:
