How many types are there in java?
The two basic data types in Java are primitives and objects. Primitives: byte, char, short, int, long, float, double, boolean Objects: Everything else.
Define an expression that evaluates to true when i equals j?
In Java, or C, the expression is simply:i == jIf the two are equal, this expression will evaluate to true; if not, it will evaluate to false.In Java, or C, the expression is simply:i == jIf the two are equal, this expression will evaluate to true; if not, it will evaluate to false.In Java, or C, the expression is simply:i == jIf the two are equal, this expression will evaluate to true; if not, it will evaluate to false.In Java, or C, the expression is simply:i == jIf the two are equal, this expression will evaluate to true; if not, it will evaluate to false.
Could array may have elements that are numbers and strings?
In Java:Not as primitives; but I believe you could create an array of Objects, and then initialize the elemnets as subtypes of the Object class, i.e., any class. I don't think this would be very practical (in Java); if (for example) you need to store information about people's names with their ages, create a class called "Person" that has those two attributes, then create an array of Persons.In Java:Not as primitives; but I believe you could create an array of Objects, and then initialize the elemnets as subtypes of the Object class, i.e., any class.

Can a java program has two different variable?
Yes. You can have as many variables as you want in Java
What is object oriented paradigm in java?
the concept of "pure" in object orientation is a little subjective and not quite well defined in practice, but there are pure object oriented programming languages. The principles of object orientation on the other hand are well defined. Programming languages are quite nested in complicated materials, and it is hard to say that everything must be an object, since all formal systems need primitives. How can you define an object without the notion of an object as a definition? This all comes down to type theory, and one can't define everything as "something" without knowing the "something". With this, Java is not actually a pure object oriented programming language since it needs primitives. The only way you can yield a pure programming language with no primitives is not even having the notion of defining concrete terms in a programming language since it doesn't have primitives in it.Smalltalk is an example of a pure programming language. With this, I can't exactly answer the question since you've presented two OO programming languages, neither of which is "pure".-Fabianski BenjaminIndia

Difference between equals equals and equal in java?
"==" 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.
Which operator is used in java script to work on string?
If you want to check if two strings are equal you have to use string_b)alert("Strings are equal");elsealert("Strings are not equal");}
How do you determine if two fractions are equal?
By reducing them to their lowest terms
How do you determine the magnitude of two equal forces?
To determine the magnitude of two equal forces, you can simply multiply the magnitude of one force by 2, as they are equal. This is because the total force is the sum of the individual forces acting in the same direction.

What is different between equals equals and equals method in java?
== (the double equal sign) is used to compare two values (resulting in true if they are equal, false otherwise). = (a single equal sign) is used to assign a value to a variable.
What is the program for compare two strings using conditional operator in java?
System.out.println(a.equals(b) ? "They are equal" : "They are different");System.out.println(a.equals(b) ? "They are equal" : "They are different");System.out.println(a.equals(b) ? "They are equal" : "They are different");System.out.println(a.equals(b) ? "They are equal" : "They are different");
How can you determine mathematically if two figures are similar?
If the two figures are the same shape. Also if the ratios of the lengths of the corresponding sides are equal.
Can a java program has two different variable?
Yes. You can have as many variables as you want in Java
What are the kinds of java programs?
the two types of java programs are Applet and application programs
