# Java Program - Find Largest Number among three Numbers

Three numbers x, y and z are given and the largest 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 largest(int x, int y, int z) {
int max = x;

if (x >= y && x >= z)
max = x;
if (y >= x && y >= z)
max = y;
if (z >= x && z >= y)
max = z;
System.out.println("largest number among " + x + ", " +
y + " and " + z + " is: " + max);
}

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

The above code will give the following output:

largest number among 100 , 50 and 25 is:  100
largest number among 50 , 50 and 25 is:  50

### Method 2: Using If-else statement

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

public class MyClass {
static void largest(int x, int y, int z) {
int max = x;

if (x >= y && x >= z)
max = x;
else if (y >= x && y >= z)
max = y;
else
max = z;

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

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

The above code will give the following output:

largest number among 100 , 50 and 25 is:  100
largest number among 50 , 50 and 25 is:  50

### 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 largest(int x, int y, int z) {
int max = x;

if (x >= y) {
if(x >= z)
max = x;
else
max = z;
}
else {
if(y >= z)
max = y;
else
max = z;
}

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

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

The above code will give the following output:

largest number among 100 , 50 and 25 is:  100
largest number among 50 , 50 and 25 is:  50

### Method 4: Using ternary operator

The ternary operator can also be used here.

public class MyClass {
static void largest(int x, int y, int z) {
int max = x;
max = (x > y)? ((x > z)? x : z) : ((y > z)? y : z);
System.out.println("largest number among " + x + ", " +
y + " and " + z + " is: " + max);
}

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

The above code will give the following output:

largest number among 100 , 50 and 25 is:  100
largest number among 50 , 50 and 25 is:  50
