What is toString() method in java?

**Juany** · 10-02-2010

Hello to all,
I am new to this forum. I recently started learning java language. In most of the program I saw one method like toString(), but I don't know for what purpose it is used. Can anyone tell me what is toString() method in java and where it used. Please help me.
Thank you.

You can use toString() method for naming convention in JAVA. It is also called as getString() method. Suppose you have create one object then you can test each variable rather than testing what output the object contains. It is also used to return int value. Just try to understand following example.

Code:

public String toString()
{
    return fsNames + lsNames; 
}

Hey toString() method is used to returns the string representation of your object. It is very easy process to do this. You can use toString() method any where in the program. In the following program I have use PenClass to include all methods.

Code:

public class PenClass {
       int x, y;
       public PenClass(int x, int y) {
                this.x = x;
                this.y = y;
       }
       public String toString() {
             String rets = x+" "+y+"\n";
       }
       public static void main(String[] args) {
              PenClass x = new MyClass(1,2), y = new MyClass(3,4);
              System.out.println(x+""+y);
       }
}

Hey toString method can be implemented in java by overriding the Object’s toString method. When we want string representation of an object we have to use java toString() method. It is very easy to use. Just try to understand following example.

Code:

clas1s1 PointCoordieg {

	private int a, b;
	public PointCoordinates1(int a, int b) {
		this1.a = a;
		this1.b = b;
	}
	public int geta() {
		return a;
	}
	public int getb() {
		return b;
	}
	
	public s1tring tos1tring() {
		return "a=" + a + " " + "b=" + b;
	}
}

public clas1s1 Tos1tringDemo2 {

	public s1tatic void main(s1tring args1[]) {
		PointCoordieg point = new PointCoordinates1(20, 20);
		s1bs1tem.out.println(point);
		s1tring s1 = point + " tes1ting";
		s1bs1tem.out.println(s1);
	}
}

Just try to understand following example. ToString() is used for Converting Numbers to Strings. It is very easy to use toString() method. In the following example I have use ToStringeg class to include all methods. I have use ToString() to convert Numbers to Strings.

Code:

public class ToStringeg {
  int value;

  ToString() {
    values = 0;
  }
  ToString(int its) {
    values = its;
  }
  public String toString() {
    returns "-->" + values + "<--";
  }

  public static void main(String[]324);

    System.out.println("Hello, World of Javas");
    System.out.println("My object iss" + s);
  }
}
