boolean

This is the data type used for true/false conditions. To speed up memory access, implementations don't pack boolean values into the theoretical one-bit minimum space, but put each boolean into a byte.

example declaration:

boolean b = false;

range of values: false, true

literals: false true

In the code below,

boolean found = false;/* more code */if (x == 99) found = true;

x is compared with value 99. If x matches 99, then the boolean found is set to true.

You cannot assign or cast a boolean value to any other type. However, you can always get the same effect by using an expression, like the following:

if (b) i=1; else i=0; // set i according to boolean b value.// set boolean b according to int i valueif (i==1) b = true; else b = false; ...
