- Calculating Volume
You are given a class Solution and its main method in the editor. In each test cases, it takes an input which represents a choice of the following:
- represents the volume of a cube that has to be calculated where represents the length of the sides of the cube.
- represents the volume of a cuboid that has to be calculated where represent the dimensions of a cuboid.
- represents the volume of a hemisphere that has to be calculated where represents the radius of a hemisphere.
- represents the volume of a cylinder that has to be calculated where represent the radius and height of the cylinder respectively.
Your task is to create the class Calculate and the required methods so that the code prints the volume of the figures rounded to exactly decimal places.
In case any of the dimensions of the figures are , print "java.lang.NumberFormatException: All the values must be positive" without quotes and terminate the program.
Note: Use Math.PI or as the value of pi.
First line contains , the number of test cases. Each test case contains ch, representing the choice as given in the problem statement.
- When ch=1, Next line contains , length of the sides of the cube.
- When ch=2, Next three lines contain , , representing length, breadth and height of the cuboid respectively. , , will be in three separate lines
- When ch=3, Next line contains , the radius of the hemisphere
- When ch=4, Next two lines contain , representing the radius and height of the cylinder respectively. , will be in two separate lines.
Note: You have to determine the data type of each parameter by looking at the code given in the main method.
There will be at most digits after decimal point in input.
For each test case, print the answer rounded up to exactly 3 decimal places in a single line. For example, 1.2345 should be rounded to 1.235, 3.12995 should be rounded to 3.130.
Sample Input 1
2 1 4 4 67.89 -98.54
Sample Output 1
64.000 java.lang.NumberFormatException: All the values must be positive
There are two test cases. In the first test case , means you have to calculate the volume of a cube. The next line contains the =4, means the side of the cube is . So the volume of the cube is .
In the second test case, you have to calculate volume of a cylinder. But the height of the cylinder is negative, so an exception is thrown.
