Can anyone help me with Java code?

import java****.PrintStream;

	}

		String name, num, time;
		
		if(!sc.hasNext()) return null;
		name = sc.nextLine();
		
		if(!sc.hasNext()) return null;
		num = sc.nextLine();
		
		if(!sc.hasNext()) return null;
		time = sc.nextLine();
		
		return new Horse(name, num, time);
		
	}
	
	public String getName() {
		return name;
	}
	public void setName(String name) {
		this.name = name;
	}
	public String getNum() {
		return num;
	}
	public void setNum(String num) {
		this.num = num;
	}
	public String getTime() {
		return time;
	}
	public void setTime(String time) {
		this.time = time;
	}


	public void print (PrintStream ps){

	}

	private String name;
