Write the Java expression to find the sum of cube root of \(x\) and the absolute value of \(y\).
Show Hint
Solution and Explanation
We need two operations here:
\[ \text{cube root of } x \] and
\[ \text{absolute value of } y \] Step 2: Recall the Java methods.
In Java, the cube root is found using \texttt{Math.cbrt(x)} and the absolute value is found using \texttt{Math.abs(y)}.
Step 3: Add both expressions.
Therefore, the required Java expression is:
\[ \texttt{Math.cbrt(x) + Math.abs(y)} \]
Top Questions on Operators
- Evaluate the Java expression:
\[ x = a * b % (++c) + (++a) + (--b); \] if \(a = 7\), \(b = 8\), \(c = 2\). - Assertion (A): The result of the Java expression \(3 + 7/2\) is \(6\).
Reason (R): According to the hierarchy of operators in Java, addition is done first followed by division. - What is the output of the statement Math.pow(36, 6/5) ?
- The output of the statement: \texttt{System.out.println(Character.toUpperCase('b') + 2); is:}
- Union, intersection and minus can be applied between two tables if :

Assertion and Reasoning
Assertion (A): The substring() method modifies the original String.
Reason (R): The substring() method can extract part of a String from a specific index.

Rewrite the following program segment using a
forloop:Given program segment:
int a = 5, b = 10;
while (b > 0)
{
b -= 2;
}
System.out.println(a * b);Note: Ensure that the variable $b$ remains accessible for the

- Object-Oriented Programming
- Write a program to accept a two-dimensional integer array of order \( 4 \times 5 \) as input from the user. Check if it is a Sparse Matrix or not. A matrix is considered to be a sparse, if the total number of zero elements is greater than the total number of non-zero elements. Print appropriate messages.
