What would be the result of attempting to compile and run the following code?
public class HelloWorld{
public static void main(String[] args){
double[] x = new double[]{1, 2, 3};
System.out.println("Value is " + x[1]);
}
}
public class HelloWorld{
public static void main(String[] args){
double[] x = new double[]{1, 2, 3};
System.out.println("Value is " + x[1]);
}
}A. The program has a compile error because the syntax new double[]{1, 2, 3} is wrong and it should be replaced by {1, 2, 3}.
B. The program has a compile error because the syntax new double[]{1, 2, 3} is wrong and it should be replaced by new double[3]{1, 2, 3};
C. The program has a compile error because the syntax new double[]{1, 2, 3} is wrong and it should be replaced by new double[]{1.0, 2.0, 3.0};
D. The program compiles and runs fine and the output
Answer: Option D
Solution (By Examveda Team)
new double[]{1, 2, 3} is correct. This is the syntax I have not covered in this edition, but will be covered in the future edition. In this question, double[] x = new double[]{1, 2, 3} is equivalent to double[] x = {1, 2, 3};
This Question Belongs to Java Program >> Array
class Comp2 {
public static void main(String[] args) {
float f1 = 2.3f;
float[][] f2 = {{42.0f}, {1.7f, 2.3f}, {2.6f, 2.7f}};
float[] f3 = {2.7f};
Long x = 42L;
// insert code here
System.out.println(""true"");
}
}
If I run the same, It will definitely show me some error.
Value is 2.0
Your Answer is incorrect try to run it and then see it
