Java中的 IntStream codePoints() 方法及示例

IntStream类的codePoints()方法用于从给定序列中获取代码点值流。它返回作为参数传递的字符的 ASCII 值

句法：

public IntStream codePoints()

返回值：此方法返回IntStream 代码值

下面的示例说明了 codePoints() 方法的使用：

示例 1：

// Java program to demonstrate
// codePoints() method of IntStream class
  
import java.util.stream.IntStream;
  
public class GFG {
    public static void main(String args[])
    {
  
        // String to be converted
        String str = "GeeksForGeeks";
  
        // Convert the string to code values
        // using codePoints() method
        IntStream stream = str.codePoints();
  
        System.out.println("ASCII Values are: ");
  
        // Print the code points
        stream.forEach(System.out::println);
    }
}

输出：

ASCII Values are: 
71
101
101
107
115
70
111
114

示例 2：

// Java program to demonstrate
// codePoints() method of IntStream class
  
import java.util.stream.IntStream;
  
public class GFG {
    public static void main(String args[])
    {
  
        // String to be converted
        String str = "A computer science"
                     + " portal for geeks";
  
        // Convert the string to code values
        // using codePoints() method
        IntStream stream = str.codePoints();
  
        System.out.println("ASCII Values are: ");
  
        // Print the code points
        stream.forEach(System.out::println);
    }
}

输出：

ASCII Values are:
