The .or() and .like() methods in Java are used in conjunction with SQL queries to create more complex and specific search conditions.
The .or() method is used to combine multiple search conditions in a SQL query. For example:
```
SELECT * FROM customers WHERE name = 'John' OR city = 'New York';
```
This query will return all customers whose name is John or who live in New York.
The .like() method is used to search for a pattern within a string. For example:
```
SELECT * FROM products WHERE name LIKE '%chair%';
```
This query will return all products whose name contains the word "chair". The % symbol is a wildcard that can represent any number of characters before or after the search term.
Together, these methods can be used to create complex SQL queries that search for specific data in a database.
