Java SE 8 Programmer I — Question 184

Which two code fragments cause a compilation error? (Choose two.)

Answer options

• A. float flt = 100.00F;
• B. float flt = (float) 1_11.00;
• C. Float flt = 100.00;
• D. double y1 = 203.22; float flt = y1;
• E. int y2 = 100; float flt = (float) y2 ;

Correct answer: C, D

Explanation

Option C causes a compilation error because 'Float' is an object wrapper type and cannot be assigned directly like a primitive type. Option D leads to a compilation error as you cannot directly assign a double value to a float variable without an explicit cast. Options A, B, and E are correctly defined and do not cause compilation issues.
