# JAVA program that checks if a triangle is scalene, isosceles, equilateral, or not a triangle

I am trying to write java program to see if a triangle is scalene, isosceles, equilateral or not a triangle. With the integers I used it is supposed to be not a triangle (1, 1, 30). But I keep getting scalene and not a triangle together. Any help is appreciated! Thank you!

```public class Tri {

static void checkTriangle(int x, int y, int z)
{

// Check for equilateral triangle
if (x == y && y == z )
System.out.println("Equilateral Triangle");

// Check for isoceles triangle
else if (x == y || y == z || z == x )
System.out.println("Isoceles Triangle");

// Check for scalene triangle
else if (x != y || y!= z || z != x)
System.out.println("Scalene Triangle");
{
// Check for not a triangle
if (x + y < z || x + z < y || y + z > x)
System.out.println("Not a triangle");

}
}

public static void main(String[] args) {
{

int x = 1, y = 1, z = 30;

checkTriangle(x, y, z);
}
}
}
```

You should check for not a triangle condition first. As below:

```static void checkTriangle(int x, int y, int z)
{

// Check for not a triangle
if (x + y < z || x + z < y || y + z > x) {
System.out.println("Not a triangle");
} else {

// Check for equilateral triangle
if (x == y && y == z )
System.out.println("Equilateral Triangle");

// Check for isoceles triangle
else if (x == y || y == z || z == x )
System.out.println("Isoceles Triangle");

// Check for scalene triangle
else if (x != y || y!= z || z != x)
System.out.println("Scalene Triangle");
}
}

public static void main(String[] args) {
{

int x = 1, y = 1, z = 30;

checkTriangle(x, y, z);
}
}
}
```
