Placing the array designators [] after the type helps maintain backward compatibility with older versions of the Java SE platform.
This syntax contributes to better readability as it becomes easier to distinguish between array types and non-array types. It helps convey the
intention of the method to both the developer implementing it and the developer using it.
Noncompliant code example
public class Cube {
private int magicNumbers[] = { 42 }; // Noncompliant
public int getVector()[] { /* ... */ } // Noncompliant
public int[] getMatrix()[] { /* ... */ } // Noncompliant
}
Compliant solution
public class Cube {
private int[] magicNumbers = { 42 }; // Compliant
public int[] getVector() { /* ... */ } // Compliant
public int[][] getMatrix() { /* ... */ } // Compliant
}
