Both languages have booleans. Java uses true and false whereas Python uses True and False and any value (all values are true other than False, 0, and "").
Python's Boolean operators: and, or, and not are replaced by: &&, || and ! in Java.
Operators in Java ! (x > 0 && y > 0) || z > 0 ^ w > 0 | Operators in Python not(x > 0 and y > 0) or z > 0 |
The comparison operator for numbers are the same as in Python. For built-in types, instead of == in Python, Java uses equals method.
In Java, most of the comparison operators ( >, <, >=, and <=) can be applied only to primitive types, while in Python, the comparison operators can be applied to numbers, strings, and other types of objects, and compare values in some appropriate way (e.g. numeric order, lexical order) where possible.. Two (== and !=) can be applied to any object, but when applied to reference types they test for same (different) object rather than same (different) value.
Strings in Java boolean x = true; boolean y = false; // Output: x and y is false System.out.println("x and y is " + (x && y)); // Output: x or y is true System.out.println("x or y is " + (x || y)); // Output: not x is false System.out.println("not x is " + !x); | Logical Operators in Python x = True y = False # Output: x and y is False print('x and y is',x and y) # Output: x or y is True print('x or y is',x or y) # Output: not x is False print('not x is',not x) |
Negation is also formed differently between those two programming languages
Negation in Java int x = 10; int y = 12; // Output: x > y is false System.out.println("x > y is " + (x>y)); // Output: x < y is true System.out.println("x < y is " + (x<y)); // Output: x == y is false System.out.println("x == y is " + (x==y)); // Output: x != y is true System.out.println("x != y is " + (x!=y)); // Output: x >= y is false System.out.println("x >= y is " + (x>=y)); // Output: x <= y is true System.out.println("x <= y is " + (x<=y)); | Comparison operators in Python x = 10 y = 12 # Output: x > y is False print('x > y is',x>y) # Output: x < y is True print('x < y is',x<y) # Output: x == y is False print('x == y is',x==y) # Output: x != y is True print('x != y is',x!=y) # Output: x >= y is False print('x >= y is',x>=y) # Output: x <= y is True print('x <= y is',x<=y) |
