An expression is anything that can be evaluated ("calculated"), to get a value. Numeric expressions are more common: anything that you can calculate, and get a number. For example, if a and b are numbers, a + b will give you another number - it is therefore a numeric expression. The variables by themselves are also numeric expressions.
A boolean expression is anything that you can evaluate and get a result that is boolean, i.e., either true or false. Here are some examples:
a == b
a > b
a >= 5 && a <= 10 // && means "and"
Any method that returns either true or false, for example (for the String class) the method matches(), which states whether the string does, or does not, match a certain pattern.

False will be the default value of the boolean datatype in java
A boolean or comparison in Java is made with the operator.boolean a = true;boolean b = false;if( a b) {...}A bitwise or comparison in Java is made with the | operator.int n = 1;int m = 2;if( n | m == 3 ) {...}
"The following" doesn't make sense if you don't include a list. You can find a list of Java operators, including their precendence, at http://docs.oracle.com/javase/tutorial/java/nutsandbolts/operators.html. Or search for [java operator precedence] for additional places that explain this topic.
There are a a few different websites that offer lessons on Boolean values in Java. The most reliable website is called HomeAndLearn because of its many different lessons.
Here is some sample code to convert a string into a boolean: String word = "true"; boolean boo; if (word.equalsIgnoreCase("true")) boo=true; else boo=false;
No

"==" in java is the binary operator which compares two values and gives a boolean result While "=" in java is a assignment operator which assigns a value to a variable.
The ! (boolean invert) operator returns the opposite of a boolean's current value: if(!(7 5," and the statement produces this output: not equal
The non-class Java data types are primitives: * byte * short * int * long * float * double * boolean * char
The 8 primitive data types are byte, short, int, long, float, double, boolean and char boolean is used to store logical values true/false char is used to store single digit characters. 'Y', 'X' etc the remaining data types are used to store a wide variety of numbers.
