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();
      }
      List list = Arrays.asList(name); 
      System.out.println();
      for(String li: list){
         String str = li;
         System.out.print(str + " ");
      }
   }
}
