Can someone help me with the two questions in this code (written as comments)?
public class Test {
public static void main(String[] args) {
System.out.println(max(1, 2)); }
public static double max(int num1, double num2) {
System.out.println("max(int, double) is invoked"); /* 2.1 what is the pre-condition and the post
condition here */
if (num1 > num2) return num1;
else
return num2;
} /* 2.2 what is the pre-condition and the post condition here */ public static double max(double num1, int num2) {
System.out.println("max(double, int) is invoked");
if (num1 > num2) return num1;
else
return num2;
} }
Explanation / Answer
public class Test
{
public static void main(String[] args)
{
System.out.println(max(1, 2));
}
public static double max(int num1, double num2)
{
System.out.println("max(int, double) is invoked");
/* 2.1 what is the pre-condition and the post
condition here */
/* here pre condition is num1 and num2 should have int value stored.*/
if (num1 > num2) return num1;
else
return num2;
/* depending on values in num1 and num2 the value is returned which is large*/
} /* 2.2 what is the pre-condition and the post condition here */
/* here num1 and num2 must have double value passed in it*/
public static double max(double num1, int num2)
{
System.out.println("max(double, int) is invoked");
if (num1 > num2) return num1;
else
return num2;
}
/* post condition here is that the above method returns large value among two doubles*/
}
