CD are the right ones that result in compilation error

CD are corect

The answer is C and D. A. float flt = 100.00F; // correct B. float flt = (float) 1_11.00; // correct C. Float flt = 100.00; // assigning a double to Float object without explicit cast D. double y1 = 203.22; float flt = y1; // assigning a double to a float without explicit cast E. int y2 = 100; float flt = (float) y2 ; // correct

The answer is CD

C and D are not valid.

Answer is : CD tested

Answer is CD.

Example 2; import java.util.Arrays; import java.util.Scanner; public class ArrayDefaultValues { int intArray[] = new int[3]; float floatArray[] = new float[3]; byte byteArray[] = new byte[3]; boolean boolArray[] = new boolean[3]; String stringArray[] = new String[3]; public static void main(String args[]){ ArrayDefaultValues obj = new ArrayDefaultValues(); System.out.println(Arrays.toString(obj.intArray)); System.out.println(Arrays.toString(obj.floatArray)); System.out.println(Arrays.toString(obj.byteArray)); System.out.println(Arrays.toString(obj.boolArray)); System.out.println(Arrays.toString(obj.stringArray)); } } Output [0, 0, 0] [0.0, 0.0, 0.0] [0, 0, 0] [false, false, false] [null, null, null]

Answer is CD. To test, uncomment one option at a time in the IDE and check the error. public static void main(String[] args) { //float flt = 100.00F; // A - Ok //float flt = (float) 1_11.00; // B - Ok //Float flt = 100.00; // C - Error - need cast to Float. //double y1 = 203.22; float flt = y1; // D - Error - need cast to float. //int y2 = 100; float flt = (float) y2 ; // F - Ok }

Wrong Question, because Letters A, C and D not compiles...

Correct answer is C and D

Why does C not create compilation error
