1. Using SQL Query To show the list of tables with the corresponding schema name, run this statement:

SELECT * FROM information_schema.tables;

or in a particular schema:

SELECT * FROM information_schema.tables WHERE table_schema = 'schema_name';

2. Using psql To list all tables: In all schemas:

\dt *.*

In a particular schema:

\dt schema_name.*

You forget to add // on commenting lines that is in line number 5 and 22

public class student{
private int ID;
private String Name;

//Student class constructor
student(int id, String name){
    this.ID = id;
    this.Name = name;
}
public int getid(){
    return this.ID;
}
public String Getname(){
    return this.Name;
}
public void SETid(int i){
    this.ID = i;
}
public void sETNAme(String n){
    this.Name=n;
}
// method to display data
public void display() {
    System.out.println("Student id is: " + id + " "
        + "and Student name is: "
        + Name;
    );
    System.out.println();
}
