package zen;

public class zen1
{
	public int id;
	public String name;
	public String email;
	public zen1(int id,String name,String email)
	{
		this.id=id;
		this.name=name;
		this.email=email;
	}
	public static void ze(zen1 s[])
	
	{
	
		for(zen1 t:s)
		{
			System.out.println(t.id+" "+t.name+" "+t.email);
		}
	}
	
	public static void main(String args[])
	{
		
		zen1[] s=new zen1[3];

		Scanner test=new Scanner(System.in);
		for(int i=0;i<s.length;i++)
		{
			s[i]=new zen1(test.nextInt(),test.nextLine(),test.nextLine());
			ze(s[i]);
		
		}
	}
}

Solution 1

as per

Java

public static void ze(zen1 s[])

You need to call it as ze(s);
If you want to pass single element, modify your ze method to

Java

public static void ze(zen1 s)

but that require implementation changes as well in side function.

if i use public static void ze(zen1 s) i can't able to access the array values in for-each loop.

then declare it as public static void ze(zen1 s[]) and modify your logic

That's because you declared ze as accepting a parameter that is an array of zen1 items:

public static void ze(zen1 s[])

And you are trying to pass a single zen1 instance to the method:

s[i]=new zen1(test.nextInt(),test.nextLine(),test.nextLine());
ze(s[i]);

Change the method definition to accept a single instance, or call the method outside the loop and pass the whole array:

for(int i=0;i<s.length;i++)
	{
		s[i]=new zen1(test.nextInt(),test.nextLine(),test.nextLine());
	}
ze(s);

You do not want to pass the whole array inside the loop because you do not have all elements containing actual instances until the loop is complete.
