遍歷多個目錄在Groovy

Question

同時我想遍歷多個列表如下同時：

def p = ["A", "B", "C"] 
def q = ["d", "f", "g"] 
for (x,y in p,q) { 

    println x 
    println y 

} 

我可以這樣做如下：

def p = ["A", "B", "C"] 
def q = ["d", "f", "g"] 
for (i=0; i<q.size(); i++) { 

    println p[i] 
    println q[i] 

} 

，但我很想知道解決在以前的格式。任何想法如何在groovy中實現相同？

您可以嘗試transpose：

def p = ["A", "B", "C"]; 
def q = ["d", "f", "g"]; 
for (i in [p,q].transpose()) { 
    println i[0] 
    println i[1] 
}
