I'm trying to create a simple JDBC method to delete from my DB, and I'm not sure if I'm going about this the correct way. This is inside one of my services.
Method:
public void deleteLocation(Integer id) {
String DELETE = "DELETE FROM locale WHERE id=?";
namedParameterJdbcTemplate.update(DELETE, new BeanPropertySqlParameterSource(id));
}

I would try changing your update line to
namedParameterJdbcTemplate.update(DELETE, id);.

If you are using spring-boot. Then you should be using spring-data-jpa to manage your database. Jdbc is Hard way of doing this.
If you are using jdbc delete to a specific row use prepared statement. You can refer this:
preparedStatement = connection.prepareStatement("DELETE * from table_name WHERE id= ?");
preparedStatement.setInt(1, id);
return !preparedStatement.execute();

i keep getting this error error in sql syntax check for error that corresponds to mysql manual near

Although the error message is missing, it's probably in consequence of calling an incompatible setter method for one or more parameters.
For example, an id column is usually a number. Hence, based on the data type of this column, you have to call the corresponding setter method (setInt, setLong).

PreparedStatement amovie = con.prepareStatement("INSERT INTO actor_movie(actor_ID, movie_ID)"+ "select actor_ID from actor" + "where actor.surname = 'Depp', select movie_ID from movie where movie.title LIKE 'Caribbean%'");
Can someone tell me what is wrong with this query ? I digged the internet, but can't find a solution.
Error Message :
Exception in thread "main" com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: You have an error in your SQL syntax; check the manual that corresponds to your MySQL server version for the right syntax to use near ', select movie_ID from movie where title LIKE 'Caribbean%'' at line 1

You have syntax error because you forgot VALUES and to enclose in parentheses the SELECT statements.
Change to this:
PreparedStatement amovie = con.prepareStatement(
"INSERT INTO actor_movie(actor_ID, movie_ID) VALUES ((select actor_ID from actor where actor.surname = 'Depp'), (select movie_ID from movie where movie.title LIKE 'Caribbean%'))");

Careful with the spaces needed between the strings concatenate
...movie_ID)"+ "select ...

My columns at customer table
cusid cusname cusadress paidamount email
cus123 damidu kegalle 45 adfff
This is my Java query
String query = "UPDATE `customer` SET `cusname`='"+jTextField_name.getText()+"',`cusadress`='"+jTextField_adress.getText()+"',`paidamount`='"+jTextField_amount.getText()+"',`email`="+jTextField_emailuser.getText()+" WHERE `cusid` = "+jTextField_id.getText();
executeSQlQuery(query, "Updated");
Error
com.mysql.jdbc.exceptions.jdbc4.MySQLSyntaxErrorException: Unknown column 'cus123' in 'where clause'
What is the reason for this update is not working , but insert and delete statement works?

Use PreparedStatement like this below :
String updateQuery = "UPDATE customer SET cusname=?,cusadress=?,paidamount=?,email=? WHERE cusid=?";
PreparedStatement stmt=con.prepareStatement(updateQuery); // con is reference variable of Connection class
stmt.setString(1, jTextField_name.getText());
stmt.setString(2, jTextField_adress.getText());
stmt.setInt(3, jTextField_amount.getText());
stmt.setString(4, jTextField_emailuser.getText());
stmt.setString(5, jTextField_id.getText());
Hope this helps.

Below code gives
ORA-00933: SQL command not properly ended
on
private final String DUPLICATE_SQL_1="select abc, count(abc)"
+"from table_1"
+"where type= 'NEW'"
+"and trunc(update_date) = trunc(sysdate)"
+"group by abc having count(abc)>1";
ResultSet rs = stmt.executeQuery(DUPLICATE_SQL_1);
Same query worked fine on Oracle SQL Developer.

You are missing spaces (you must have a space at the end of each line except the last or at the start of each line except the first):
private final String DUPLICATE_SQL_1="select abc, count(abc) "
+"from table_1 "
+"where type= 'NEW' "
+"and trunc(update_date) = trunc(sysdate) "
+"group by abc having count(abc)>1";
