What are the Types of Methods in Java Program - List of Methods in Java Programming

 

Java methods tutorial: 

In this given tutorial, you are going to learn about Java methods. Java program language a program may consist of one or more classes, also a class contains a method (Function in C and C++). 

In java programming main method is a must for the program execution and the method has the name and return type. 


-> public, private is the Access specifiers, to decides classes can call a method. 

-> static, synchronized are Keywords used for some particular methods. 

->Return type indicates return value, Method name is a valid Java identifier name. 

keywords, Access specifiers, and arguments are optional.

Types of  methods declaration:
public static void main(String[] args);

 * // Main method where program execution begins
 
  public static void main(String[] args) {
    staticMethod();
    Methods object = new Methods();
    object.nonStaticMethod();
  }


void myMethod();

  // Constructor method
 
  Methods() 

{
    System.out.println("Constructor method is called when an object of its class is created");
  }


private int maximum();

public synchronized int search(java.lang.Object);

  // Static method
 
  static void staticMethod() {
    System.out.println("Static method can be called without creating object");
  }
 
  // Non static method
 
  void nonStaticMethod() {
    System.out.println("Non static method must be called by creating an object");
  }
}

Java String methods:


class StringMethods
{
  public static void main(String args[])
  {
    int n;
    String s = "Java programming", t = "", u = "";
   
    System.out.println(s);
   
    // Find the length of string
   
    n = s.length();
    System.out.println("Number of characters = " + n);
   
    // Replace characters in the string
   
    t = s.replace("Java""Java Script");
    System.out.println(s);
    System.out.println(t);
   
    // Concatenating string with another string
   
    u = s.concat(" is fun");
    System.out.println(s);
    System.out.println(u);
  }
}
