Java program to check A is divisible by B?
Implement this method: public static boolean isDivisible(int a, int b) { if(a % b == 0) { return true; } else { return false; } }
Which method is default by true in java?
I don't understand what you mean with "default by true"? Please clarify your question. A Java method can have zero or more parameters, and it must have one return value. Any of these can be declared as "boolean", in which case the value can be either true or false.
How can Boolean be used in Java?
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 == ba > ba >= 5 && a ba >= 5 && a ba >= 5 && a ba >= 5 && a
How you find whether character is alphabet or not in java?
Use the Character.isLetter(char letter) method. // This line will return true Character.isLetter('a'); // This line will return false Character.isLetter('4');
Difference in using a method that return value and method that does not return value in object orinted programming?
A method that return a value should have a return statement. The method signature should indicate the type of return value. While in the case of a method that does not return a value should not have a return statement and in the signature, the return type is void. When using a method that doesn't return a value, a programmer can not get a value from that function, but instead, it can only change variable values and run other methods.
Give an example source code to find the given number is even or odd using method overloading in java?
The following will return true if the number provided is even: boolean isEven(int number) { return number % 2 == 0; } Repeat for other integral data types (such as long), and you have method overloading.The following will return true if the number provided is even: boolean isEven(int number) { return number % 2 == 0; } Repeat for other integral data types (such as long), and you have method overloading.The following will return true if the number provided is even: boolean isEven(int number) { return number % 2 == 0; } Repeat for other integral data types (such as long), and you have method overloading.The following will return true if the number provided is even: boolean isEven(int number) { return number % 2 == 0; } Repeat for other integral data types (such as long), and you have method overloading.

Why do you need to express logic functions using Boolean descriptions?
Boolean algebra is a mathematical method used to describe the behavior and operation of digital logic. Boolean descriptions and relationships can help us design logic and predict the behavior of more complex digital systems.
a)Why do we simplify Boolean expressions?
Through Boolean algebra simplification, a Boolean expression is translated to another form with less number of terms and operations. A logic circuit for the simplified Boolean expression performs the identical function with fewer logic components as compared to its original form.

How do you find out not equals string in java?
Remember that strings are objects. You can use the String.equals method to determine equality, and use the ! (not) operator to test for inequality. public static boolean notEquals(String str1, String str2) { return !str1.equals(str2); }
Why use void in main of java?
No. void is not a data type. It is mandatory for all java methods to return something and if it is not going to return anything, we have to mark the method with a "void" return type to let the JVM know that it must not expect anything from the method.
Can an overridden method return void instead of an object?
Sure. An overridden method can return anything it wants.
What does a void method do?
In Java, this keyword is used to specify that the method has no return value.
