Answer:
Option a, b, d, f, and j is legal method calls.
Explanation:
In the given question some information is missing, that is the method definition which can be described as follows:
Method definition:
int x =2, y=3; //defining integer variable
int mathMethod (int x) //method definition
{//method body
int z=x+y; //calculate value
return z; //return value
}
In the given question option a, b, d, f, and j is legal, because these options follow the correct syntax, and other option were incorrect which can be defined as follows:
- In option c, It is illegal because it accepts only one parameter.
- In option e, It is accepts long number, that's why it is illegal.
- In option g, It accepts float value, that's why it is illegal.
- In option h, It doesn't accepts any parameter.
- In option i, It isn't use in method.
Answer:
rsort()
Explanation:
the sorting function is used to sort the elements in the array.
the sorting can be increasing or decreasing, depends on the function used.
let discuss the option:
a. sort()
this is the sorting function, it used to sort the array in ascending order.
b. arsort()
this is also sorting function, it used to sort the associated array in descending order according to the value.
d. asort()
this is also sorting function, it used to sort the associated array in ascending order according to the value.
c. rsort()
this is the sorting function, it used to sort the array in descending order.
Therefore, the correct answer is rsort().
Answer:
public class TestImport{
public static void main(String[] args) {
String string1 = args[1];
String string2 = args[2];
System.out.println(string1 +" " +string2);
}
}
Explanation:
The solution here is to use string concatenation as has been used in this statement System.out.println(string1 +" " +string2);
When this code is run from the command line and passed atleast three command line arguments for index 0,1,2 respectively, the print statment will return the second string (that is index1) and the third argument(that is index2) with a space in-between the two string.
