Testarray.java
class Testarray{
static void min(int arr[]){
int min=arr[0];
for(int i=1;i
if(min>arr[i])
min=arr[i];
System.out.println(min);

public static void main(String args[]){
int a[]={33,3,4,5};
min(a);//passing array to method
}}
Example 3
Following example demonstrates to convert an array into a collection Arrays.asList(name) method of Java Util class.
import java.util.*; import java.io.*; public class ArrayToCollection{ public static void main(String args[]) throws IOException{ BufferedReader in = new BufferedReader (new InputStreamReader(System.in)); System.out.println("How many elements you want to add to the array: "); int n = Integer.parseInt(in.readLine()); String[] name = new String[n]; for(int i = 0; i < n; i++){ name[i] = in.readLine(); } Listlist = Arrays.asList(name); System.out.println(); for(String li: list){ String str = li; System.out.print(str + " "); } } }
