The two sides of a relational operator have to be compatible. The equality operators ( and ) provide the IsLooselyEqual semantic.This can be roughly summarized as follows: If the operands have the same type, they are compared as follows: Object: return true only if both operands reference the same object. The following expressions show how they are used: x = y // x is equal to y Relational operators are used to check conditions like whether two values are equal, or whether one is greater than the other. This chapter presents the features you need for programs to make decisions: a new data type called boolean, operators for expressing logic, and if statements. So you can say triple equal does not only see if both. for example: is the negation operator in java, so done, is not not done, is the same as done. But will return false reason is types of both numbers are different. you can write 'not' as '' so if done is a boolean: true or false, when its put in done it will always be done. For example if you compare ‘1’ with 1 double equal will return true. The syntax of the string equalsIgnoreCase () method is: Here, string is an object of the String class. If the strings are equal, equalsIgnoreCase () returns true.
The programs we’ve seen in previous chapters do pretty much the same thing every time, regardless of the input.įor more complex computations, programs usually react to the inputs, check for certain conditions, and generate appropriate results. Will not worry about variable type you are comparing. The Java String equalsIgnoreCase () method compares two strings, ignoring case differences.
