To invoke a non-static method, first create an object of the class, then call the method using that object.
class Example {
void greet() { // Non-static method
System.out.println("Hello, welcome to Java!");
}
public static void main(String[] args) {
Example obj = new Example(); // Create an object of the class
obj.greet(); // Call the non-static method using the object
}
}
10.6.1 Pass by Value
In call by value, a method is called by passing the value of parameters. In this type of method call, the copy of the actual
parameters is sent to the formal parameters. Let us take the following example:
To print the number is a Palindrome number or not using a method boolean palin(int). A
Program 1 Palindrome number is a number whose reverse is equal to the original number. For example,
121
1 class PalindromeCheck
2 {
3 boolean palin(int m)
4 {
5 int r=0, t=m;
6 System.out.println("Value of m before execution of loop : " + m);
7 while(m>0)
8 {
9 r= r*10+m%10;
10 m=m/10;
11 }
12 System.out.println("Value of m after execution of loop : " + m);
13 if(t==r)
14 return true;
15 else
16 return false;
17 }
