C++; } } In this method, the test condition is c <= years, when this condition is met the loop is executed. The loop counter c is defined in the normal way and explicitly incremented at the end of the loop. The behaviour is exactly the same as the previous howManyMink method You can include multiple test conditions in the while clause in the same way that you can have more than one test condition in an if. else statement. while loops are similar to while loops and in most cases they can be substituted for each other.
Bitwise XOR. Bitwise OR. Logical AND. Logical OR. These eleven operators all different forms of assignment. When operators have the same precedence, the leftmost one is carried out ftrst. println{"Hello'~ ; The Java Language 23 The System class has three fields which are using for input and output: • • • out the standard output stream. err the standard error stream. in the standard input stream. The standard output stream, out, and the error stream err are objects of the PrintStream class.

1. 24 J. 1 The comparison operators. = < > <= >= Meaning Equal. Not equal. Less than. Greater than. Less than or equal to. Greater than or equal to. One common mistake when using if statements is to confuse the assignment operator If you are unused to writing Java code this can be a hard mistake to spot the fIrst few times. To see the if statement in action we are going to look at a class called FastEnough. = with the comparison operator = =. println(speed + " MHz is too } } slow'~; This class has two int instance variables called speed and memory representing the speed and memory size of a computer.
