MUST BE WRITTEN IN JAVA

For each of the following code snippets there are multiple things wrong with the code, whether they be errorspreventing the code from compiling or errors preventing it from doing what is desired. Identify the errors andstate how they would be corrected.

(a)

Assume you have this method

public static void cubify(double x, int y)

{

double result = x*x*x + y*y*y; return result;

}

And in your main method you have the following:

int a = 3; double b = 2;

double c = cubify(a,b);

There are two errors in these snippets. What are they and how would they be fixed?

(b)

The following code snippet is supposed to print out the value of j every iteration of the inner loop, and the valueof i every iteration of the outer loop.

1. for (int i = 0; i < 10; i++)

2. {

3. for (int j = 1; j < 10; j++)

4. {

5. System.out.printf("j is %d ",j);

6. System.out.printf("i is %i ",i);

7. }

8. }

9. System.out.println("Final value of i is " + i);

Please identify 3 errors and how they can be fixed

Next Question

This code is supposed to get two double values from the user and do the following:

-If x is in the range [5,10] set BASEBALL to the String starting with Buy me ...

-Otherwise, if x is in range (10,20) OR y equals 50, set BASEBALL to the String starting with I actuallydo

-Otherwise, set BASEBALL to the String starting with Heroes are

Remember that [x,y] means the range of values from x to y including x and y (inclusive), and (x,y) means therange of values from x to y not including x and y (exclusive).

1. final String BASEBALL = "Take me out to the ball game!";

2. Scanner kb = new Scanner(System.in);

3. double x = kb.nextInt();

4. double y = kb.nextDouble();

5. if (x > 5 && x < 10)

6. BASEBALL = "Buy me some peanuts and cracker jacks";

7. else if ((x > 10 && x < 20) || y != 50)

8. BASEBALL = "I actually do care if I never come back";

9. else

10. BASEBALL = "Heroes are remembered, but legends never die";

11. }

There are five errors in this code. Identify them and explain how they can be fixed.

Consider the program segment given below. Its output is:

(a)

int x=0;

for(int i=0; i<3; i++) { for( int j=i;j<3; j++) {

x = x + j;

}

}

System.out.println( x);

(b)

int x = 2;

int y = 5;

int result = 0;

result += x+++y;

System.out.println( x + " " + y + " " + result);

(c)

int x = 1357;

int z = 0;

for( int i=x; i>0; i=i/10) {

z = z + (i%10);

}

System.out.println(z);
