A Student executes the given program segment and it results in 1.0, irrespective of the value of n. State the type of the error, write the correct statement:

void solve(int n) 
{ double power=Math.pow(n, 2/3); 
System.out.println(power); 
}

Write the return data type of the following functions:

1. startsWith()
2. random()

Give the output of the following:
       Math.sqrt(Math.max(9,16))

The output of the following code is:

System.out.println(Math.ceil(6.4) + Math.floor(-1-2));

1. 3.0
2. 4
3. 3
4. 4.0
