1. In programming, the first line of a method definition that includes the return type, method name, and parameters
The method header 'public void calculateSum(int a, int b)' specifies that the method is public, returns nothing, and accepts two integer parameters.
A assinatura do método 'public void calcularSoma(int a, int b)' especifica que o método é público, não retorna nada e aceita dois parâmetros inteiros.
2. The declaration portion of a method that defines its signature and visibility modifiers
The method header must match the implementation to avoid compilation errors.
A assinatura do método deve corresponder à implementação para evitar erros de compilação.
This is a technical term primarily used in programming education and software development contexts. It is standardized across both American and Brazilian technical communities, with 'assinatura do método' being the accepted Portuguese equivalent in both regions.
