creating object for class triangle

Define a class named triangle as described below:

Data members: 1) side1
2) Side2
3) side3
4) angle1, angle2, angle3

Methods : 1) constructors
2) trianglePerimeter()
3) triangleArea()
4) isoceles( )
5) equilateral( )
6) rightAngled()
7) scalene()

Test this class by creating an object for the class triangle.




class triangle{ 
public double s1; 
public double s2; 
public double s3; 
public double a1; 
public double a2; 
public double a3; 
public triangle(){ 
} 
public double trianglePerimeter(){ 
return this.s1+this.s2+this.s3; 
} 
public double triangleArea(){ 
double s = trianglePerimeter()/2; 
double a=s*(s-this.s1)*(s-this.s2)*(s-this.s3); 
return Math.pow(a, 0.5); 
} 
public void isisoceles(){ 
if(this.s1==this.s2 || this.s2==this.s3 || this.s3==this.s1) 
System.out.println("Triangle is isosceles."); 
else
System.out.println("Triangle is not isosceles."); 
} 
public void equilateral(){ 
if(this.s1==this.s2 && this.s2==this.s3 && this.s3==this.s1) 
System.out.println("Triangle is Equilateral."); 
else
System.out.println("Trianlge is not Equilateral."); 

} 
public void rightAngled(){ 
if(this.a1==90 || this.a2==90 || this.a3==90) 
System.out.println("Triangle is Right angled."); 
else
System.out.println("Trianle is not Right angled."); 
} 
public void scalene(){ 
if(this.a1!=this.a2 || this.a2!=this.a3 || this.a3!=this.a1) 
System.out.println("Triangle is scalene."); 
else
System.out.println("trianlge is not scalene."); 
} 
} 
class triangleClass{ 
public static void main(String[] args) { 
triangle t = new triangle(); 
t.a1=90; 
t.a2=45; 
t.a3=45; 
t.s1=12; 
t.s2=25; 
t.s3=16; 
System.out.println("The perimeter of the triangle is "+t.trianglePerimeter()); 
System.out.println("The area of the trianle is "+t.triangleArea()); 
t.isisoceles(); 
t.equilateral(); 
t.rightAngled(); 
t.scalene(); 
} 
}



OUTPUT:

The perimeter of the triangle is 53.0
The area of the trianle is 77.79419965524421
Triangle is not isosceles.
Trianlge is not Equilateral.
Triangle is Right angled.
trianlge is not scalene.

SQL Constraints, NOT NULL, UNIQUE, PRIMARY KEY, FOREIGN KEY, CHECK, DEFAULT, CREATE INDEX

SQL Constraints (Image by - Sharma Guides | Subham232330) Constraints   |   |- CHECK   |   |- NOT NULL   |   |- UNIQUE   |   |- PRIMARY KEY   |   |- DEFAULT   |   |- FOREIGN KEY   |   |- INDEX * These constraints are also known as Integrity Constraints . * SQL Constraints:- Constraints are the rules and restrictions applied to the data in a table. * NOT NULL:- Value cannot be Null in a column. * UNIQUE:- Value cannot be the same in a column. * PRIMARY KEY:- Used to uniquely identify a row. * FOREIGN KEY:- References a row in another table. * CHECK:- Satisfies a specific condition. * DEFAULT:- Set default value. * CREATE INDEX:- Used to speed up the reading process.

Write a java program which has various types of constructor and overload these constructors when the object is being created of that class.
