Java program to find largest number in an array


    This example shows you how to find largest or maximum number in an array

    Step 1:

            Initialize array value

    Step 2:  (int max = a[0];)

            Initialize max value as array's first value

    Step 3: (for int i = 1; i < a.length; i++ )

            Iterate array using a for loop (exclude arrays first position 0, since it was assumed as max value)

    Step 4: if(a[i] > max)

            Use if condition to compare array current value with max value, if current array value is greater than max then assign array current value as max (max = a[i];).

    Step 5:

            Continue the loop and resign the max value if array current value is greater than max

Program

class LargestNumber
{
	public static void main(String args[])
	{
		int[] a = new int[] { 20, 30, 50, 4, 71, 100};
		int max = a[0];
		for(int i = 1; i < a.length;i++)
		{
			if(a[i] > max)
			{
				max = a[i];
			}
		}
		
		System.out.println("The Given Array Element is:");
		for(int i = 0; i < a.length;i++)
		{
			System.out.println(a[i]);
		}
		
		System.out.println("From The Array Element Largest Number is:" + max);
	}
}


Output

The Given Array Element is:
20
30
50
4
71
100
From The Array Element Largest Number is:100
