# Bucles anidados

A linguaxe Java ofrece a posibilidade de anidar bucles dentro de outros, esta é unha posibilidade interesante para procesar estructuras de datos multidimensionais e resolver probelas que requiren iteracións complexas.

```java
    for (int i=0; i<3; i++){
            for (int j=0; j<3; j++){
                System.out.println("i: " + i + ", j: "+ j);
            }
        }
//SAIDA
i: 0, j: 0
i: 0, j: 1
i: 0, j: 2
i: 1, j: 0
i: 1, j: 1
i: 1, j: 2
i: 2, j: 0
i: 2, j: 1
i: 2, j: 2
```

Os bucles anidados son útiles para recorrer **arrays ou listas multidimensionales, xerar patróns de figuras ou combinacións de valores.**

## Consideracións

**Complexidade:** Os bucles anidados incrementan a complexidade temporal (O(n²) para dous bucles, O(n) para un)

**Lexibilidade:** É importante manter o código lexible con nomes de variables descritivos
