Question: using java Evaluate expressions, e.g. (3 < 4) evaluates to boolean value true, (3 + 4) evaluates to int value 7, hello+3+4 evaluates to String

  • using java
  • Evaluate expressions, e.g. (3 < 4) evaluates to boolean value true, (3 + 4) evaluates to int value 7, "hello"+3+4 evaluates to String value "hello34". Expressions are composed of operands and operators. Operands may be variables, values and values returned by method calls. Operators may include logical operators (&&, ||, !), equality operators (==, !=), relational operators (<, <=, >, >=), assignment operator (=), arithemetic operators (+, -, *, /, %), integer vs. floating point operations (e.g. 7/2 evaluates to 3, 7.0/2 evaluates to 3.5, 7/2.0 evaluates to 3.5, 7.0/2.0 evaluates to 3.5), data conversion (widening vs narrowing e.g. casting: (double)7/2 evaluates to 7.0/2 = 3.5).
