java - Skip over inputing string

int id;

float grade; 
String name;
Scanner z= new Scanner(System.in);
System.out.println("Give the id:\n");
id=z.nextInt();
System.out.println("your id is :"+id+"\n");

System.out.println("Give the name:");
name=z.nextLine();
System.out.println("your name is :"+name);


System.out.println("Give the grade:\n");
grade=z.nextFloat();

The problem goes like this.It inputs the integer but when it comes to the String, it prints "Give the name" but it doesn't waits until I type something, it skips to the next instruction.

Why's that?

Answer

The problem is with the input.nextInt() command it only reads the int value. So when you continue reading with input.nextLine() you receive the "\n" Enter key. So to skip this you have to add the input.nextLine()

id  = z.nextInt();
System.out.println ("your id is :"+id+"\n");
z.nextLine ();// add this line between the next line read

System.out.println("Give the name:");

or

id = Integer.parseInt(z.nextLine());
System.out.println ("your id is :"+id+"\n");
System.out.println("Give the name:");
