Java IntStream codePoints()用法及代码示例

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

用法:

public IntStream codePoints()

返回值：此方法返回IntStream代码值

以下示例说明了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
71
101

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:
