Question

this is a jave program please help, I'm so lost

import java.util.Scanner;

public class TriangleArea {
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
  
Triangle triangle1 = new Triangle();
Triangle triangle2 = new Triangle();

// Read and set base and height for triangle1 (use setBase() and setHeight())
  
// Read and set base and height for triangle2 (use setBase() and setHeight())
  
// Determine larger triangle (use getArea())
  
private int base;
private int height;
private int area;

public Triangle(int b, int h){
// Assign values passed to the constructor to the variables
base = b;
height = h;
  
area=(base*height)/2;
}
public int getBase(){
return base;
}
public void setBase(int b){
base =b;
}
public void print(){
System.out.println("The area of a triangle with the base" +base+ "and the height" +height+ "is: " +area);
}
}
  
System.out.println("Triangle with larger area:");
// Output larger triangle's info (use printInfo())
  
}
}

public class Triangle {
private double base;
private double height;

public void setBase(double userBase){
base = userBase;
}
public void setHeight(double userHeight) {
height = userHeight;
}

public double getArea() {
double area = 0.5 * base * height;
return area;
}

public void printInfo() {
System.out.println("Base: " + base);
System.out.println("Height: " + height);
System.out.println("Area: " + getArea());
}
}

Hey,

Note: Brother in case of any queries, just comment in box I would be very happy to assist all your queries

import java.util.Scanner;
class Triangle {
private double base;
private double height;
private double area;

public Triangle(int b, int h){
// Assign values passed to the constructor to the variables
base = b;
height = h;
  
area=(base*height)/2;
}
public Triangle(){
// Assign values passed to the constructor to the variables
base = 0;
height = 0;
  
}

public double getBase(){
return base;
}
public double getHeight(){
return height;
}
public double getArea() {
double area = 0.5 * base * height;
return area;
}
public void setBase(double userBase){
base = userBase;
}
public void setHeight(double userHeight) {
height = userHeight;
}
public void print(){
System.out.println("The area of a triangle with the base" +base+ "and the height" +height+ "is: " +area);
}

}

public class TriangleArea {
public static void printInfo(Triangle triangle1,Triangle triangle2) {
System.out.println("Triangle with larger area:");
double base,height,area;
  
if(triangle1.getArea()>triangle2.getArea())
{
base=triangle1.getBase();
height=triangle1.getHeight();
area=triangle1.getArea();
}
else
{
base=triangle2.getBase();
height=triangle2.getHeight();
area=triangle2.getArea();
}
System.out.println("Base: " + base);
System.out.println("Height: " + height);
System.out.println("Area: " + area);
}
public static void main(String[] args) {
Scanner scnr = new Scanner(System.in);
  
Triangle triangle1 = new Triangle(3,5);
Triangle triangle2 = new Triangle(3,7);

triangle1.setBase(3);
triangle1.setHeight(5);
triangle2.setBase(3);
triangle2.setHeight(7);

printInfo(triangle1,triangle2);

}
  
// Output larger triangle's info (use printInfo())
  
}

Kindly revert for any queries

Thanks.
