Question

我想跳过第一行的第一列并将每个元素与字符串进行比较。 Java代码

 String csvFileToRead = "C:\\Users\\Dell\\Downloads\\Tasks.csv";        
            BufferedReader br = null; 
            String[] Task = null;
            String line;  
              String splitBy = ",";
              br = new BufferedReader(new FileReader(csvFileToRead)); 
              System.out.println("Excel data for Subejct: ");
            while ((line = br.readLine()) != null) {            
                Task = line.split(splitBy); 
                System.out.println(Task[0]);    
               }

Answer 1

要跳过第一行，只需执行br.readLine()。要跳过第一列，请在1而不是0处迭代单元格。

见这个例子：

br.readLine(); //skips the first row
while ((line = br.readLine()) != null) {
    String[] cells = line.split(splitBy);
    //starting from 1 essentially skips the first column
    for (int col = 1; col < cells.length; col++) {
        if (cells[col].equals(someString)) {
            //do something
        }
    }
}

为循环添加一个br.readLine() outise，用于行跳转。打印所有cols但第一个cols：

for(int i = 1; i < Task.lenght ; ++i){
 System.out.println(Task[i]);
}

在java中读取csv时如何跳过第一行
