Hello
I am trying to complete 3.1 of Lab 1011. Below is 3.1:
4. (For your own exercise) Modify TestPassByValue.java as following. Build
and run the project.
* Pass the second primitive type parameter to the test(..) method -
you can choose any primitive type parameter (such as long or boolean).
* Set the value of the second parameter before calling the test(..)
method. And change the value of the passed parameter within the test(..)
method as you did with the first parameter in Code-3.11 above.
* Modify the System.out.println(..) methods in the Code-3.11 above to
display the values of both the first parameter and second parameter.
Here is my code:
public class TestPassByValue {
/**
* @param args the command line arguments
*/
public static void main(String[] args) {
// TODO code application logic here
int i = 10;
long k = 500;
// Print the value of i
System.out.println("start of the main method and i = " + i);
System.out.println("start of the main method and k = " + k);
// Call method test, which is defined below
// and pass int value as a parameter. Since
// int is a primitive type, this parameter is passed
// by value.
test( i );
test( k );
// print the value of i. please note that i not changed
System.out.println("end of the main method and i = " + i);
System.out.println("end of the main method and k = " + k);
}
// Another static method in the TestPassByValue class
public static void test(int j, long m){
System.out.println("start of the test method and j = " + j);
System.out.println("start of the test method and m = " + m);
// change value of parameter i
j = 33;
m = 501;
System.out.println("end of the test method and j = " + j);
System.out.println("end of the test method and m = " + m);
}
}
It indicates errors for the following lines
test( i );
required Int, long
found: int
test( k );
required Int, long
found: int
Shouldn't it be able to accept either int or long? Thanks for any help.
