Every local variable declaration statement is contained by a block ({ … }). We can also declare the local variables in the header of a “for” statement. In this case it is executed in the same manner as if it were part of a local variable declaration statement. For example:for(int ...
Any variable when declared with the keyword “static” is known as static variable or class variable in JAVA. Static variable is used to fulfill the common properties of all objects. For example: institute name of students is common for all students so it will be declared as static variable ...
Example 2: Static Variable can be accessed directly in a static method classJavaExample{staticintage;staticStringname;//This is a Static Methodstaticvoiddisp(){System.out.println("Age is: "+age);System.out.println("Name is: "+name);}// This is also a static methodpublicstaticvoidmain(Str...
The below-given syntax is used for the checking type of variable in Java: s.getClass().getSimpleName() Here, the “s” is the variable whose type will be checked using the “getSimpleName()” method. Example We will now consider the same String “s” created in the previous example ...

Example: publicclassExample{publicstaticvoidmain(String []args){intx;intval =2;if(val%2!=0) { x =100; }intans = x +10;// Using a conditionally initialized variableSystem.out.println(ans); } } Output: java: variable x might not have been initialized ...
For example, we created a reference of String class in main() method as local reference variable. 1 2 3 4 5 6 7 8 9 10 public class Demo { public static void main(String[] args){ // Local reference variables String str2 = "Java2blog"; System.out.println("Value of str2 :...
(three dots) is used in the formal parameter of a method. A method that takes variable number of arguments is called a variable-arity method, or simply a varargs method. First, let’s look at the example without using varargs: class NoVararg { public int sumNumber(int a, int b){ ret...

In Java, for example, one can write static void print_lines(String foo, String… lines) { System.out.println(“First argument is \”“ + foo + ”\“.”); System.out.println(“There are ” + lines.length + “ additional arguments:”); for (String str: lines) { System.out.println...
