I know its very simple question. but I would like to know the stringformat for boolean operator. For example, below shows the string formats for integer, string and float. what could be for boolean operator true/false?
System.out.printf("The value of the float " + "variable is %f, while " + "the value of the " + "integer variable is %d, " + "and the string is %s", floatVar, intVar, stringVar);

Java boolean operators are denoted by |, ||, &, &&, <, >, <=, >=, ^, != , ==. These logical boolean operators help in specifying the condition that will have the two return values – “true” or “false”.
If Statement The simplest if-statement has two parts -- a boolean "test" within parentheses ( ) followed by "body" block of statements within curly braces { }. The test can be any expression that evaluates to a boolean value -- true or false.
To convert String to Boolean, use the parseBoolean() method in Java. The parseBoolean() parses the string argument as a boolean. The boolean returned represents the value true if the string argument is not null and is equal, ignoring case, to the string "true".
The println(boolean) method of PrintStream Class in Java is used to print the specified boolean value on the stream and then break the line. This boolean value is taken as a parameter.
'b' or 'B' general If the argument arg is null, then the result is "false". If arg is a boolean or Boolean, then the result is the string returned by String.valueOf(arg). Otherwise, the result is "true". java docs : http://docs.oracle.com/javase/7/docs/api/java/util/Formatter.html#syntax
