Consider the following code segment.   int one = 1; int two = 2;String zee = “Z”; System.out.println(one + two + zee);   What is printed as a result of executing the code segment?

Consider the following method that is intended to determine if the double values d1 and d2 are close enough to be considered equal. For example, given a tolerance of 0.001 , the values 54.32271 and 54.32294 would be considered equal. /** 0return true if d1 and d2 are within the specified tolerance, *false otherwisepublic Boolean almostEqual(double d1, double d2, double tolerance){ /* missing code */} Which of the following should replace / * missing code * / so that almostEqual will work as intended?
