Which two cause a compiler error? 1 float f = new float(3); 2 float f2 = new float; 3 floatf1 = new float; 4 float f3 = new float; 5 float f5 = {1.0f, 2.0f, 2.0f};

(1) causes two compiler errors ( '[' expected and illegal start of expression) because the wrong type of bracket is used, ( ) instead of [ ]. The following is the correct syntax: float[ ] f = new float[3];

(2) causes a compiler error ( '{' expected ) because the array constructor does not specify the number of elements in the array. The following is the correct syntax: float f2[ ] = new float[3];

(3), (4), and (5) compile without error.
