# toString() — Core Java

Source: https://www.geekswithgeeks.com/en/core-java/java-tostring

> Override toString() for readable debug output and logging instead of the default ClassName@hashcode gibberish.

## Why override it

The default `toString()` prints `ClassName@hexHashCode` — useless for debugging. `System.out.println(obj)`, string concatenation, and most logging frameworks call `toString()` automatically, so a good one pays off everywhere.

## A useful override

Keep it concise and include the fields that identify the object. Modern `record` types (Java 16+) generate a sensible `toString()`, `equals()` and `hashCode()` automatically.

```java
@Override public String toString() {
    return "Point[x=" + x + ", y=" + y + "]";
}

// Or skip all the boilerplate with a record:
record Point(int x, int y) {}
System.out.println(new Point(1, 2));  // Point[x=1, y=2]
```
