Java IntStream codePoints()方法及示例

IntStream类的 codePoints() 方法是用来从给定的序列中获取码点值的流。它返回作为参数的字符的ASCII值。

语法

public IntStream codePoints()

返回值： 该方法返回IntStream代码值。

下面的例子说明了codePoints()方法的使用。

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
71
101

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:
