# Java Program - Find Smallest Number among three Numbers

Three numbers x, y and z are given and the smallest number among these three numbers can be found out using below methods.

### Method 1: Using If statement

In the example below, only if conditional statements are used.

```public class MyClass {
static void smallest(int x, int y, int z) {
int min = x;

if (x <= y && x <= z)
min = x;
if (y <= x && y <= z)
min = y;
if (z <= x && z <= y)
min = z;

System.out.println("Smallest number among " + x + ", " +
y + " and " + z + " is: " + min);
}

public static void main(String[] args) {
smallest(100, 50, 25);
smallest(50, 50, 25);
}
}
```

The above code will give the following output:

```Smallest number among 100 , 50 and 25 is:  25
Smallest number among 50 , 50 and 25 is:  25
```

### Method 2: Using If-else statement

It can also be solved using If-else conditional statements.

```public class MyClass {
static void smallest(int x, int y, int z) {
int min = x;

if (x <= y && x <= z)
min = x;
else if (y <= x && y <= z)
min = y;
else
min = z;

System.out.println("Smallest number among " + x + ", " +
y + " and " + z + " is: " + min);
}

public static void main(String[] args) {
smallest(100, 50, 25);
smallest(50, 50, 25);
}
}
```

The above code will give the following output:

```Smallest number among 100 , 50 and 25 is:  25
Smallest number among 50 , 50 and 25 is:  25
```

### Method 3: Using Nested If-else statement

The above problem can also be solved using nested if-else conditional statements.

```public class MyClass {
static void smallest(int x, int y, int z) {
int min = x;

if (x <= y) {
if(x <= z)
min = x;
else
min = z;
}
else {
if(y <= z)
min = y;
else
min = z;
}

System.out.println("Smallest number among " + x + ", " +
y + " and " + z + " is: " + min);
}

public static void main(String[] args) {
smallest(100, 50, 25);
smallest(50, 50, 25);
}
}
```

The above code will give the following output:

```Smallest number among 100 , 50 and 25 is:  25
Smallest number among 50 , 50 and 25 is:  25
```

### Method 4: Using ternary operator

The ternary operator can also be used here.

```public class MyClass {
static void smallest(int x, int y, int z) {
int min = x;
min = (x < y)? ((x < z)? x : z) : ((y < z)? y : z);
System.out.println("Smallest number among " + x + ", " +
y + " and " + z + " is: " + min);
}

public static void main(String[] args) {
smallest(100, 50, 25);
smallest(50, 50, 25);
}
}
```

The above code will give the following output:

```Smallest number among 100 , 50 and 25 is:  25
Smallest number among 50 , 50 and 25 is:  25
```
