java.nio.CharBuffer类的chars()方法用于从此序列返回int zero-extending char值的流。映射到代理代码点的任何字符都将通过未解释的传递。当终端流操作开始时,流将绑定到此序列(特别是对于可变序列,流的分隔符是后期绑定)。如果在该操作期间修改了序列,则结果不确定。
用法:
public IntStream chars()
返回值:此方法从此序列返回一个char值的IntStream。
下面是说明chars()方法的示例:
范例1:
// Java program to demonstrate
// chars() method
import java.nio.*;
import java.util.*;
import java.util.stream.IntStream;
public class GFG {
public static void main(String[] args)
{
// creating object of CharBuffer
// and allocating size capacity
CharBuffer charbuffer
= CharBuffer.allocate(3);
// append the value in CharBuffer
// using append() method
charbuffer.append('a')
.append('b')
.append('c')
.rewind();
// print the CharBuffer
System.out.println("Original CharBuffer: "
+ Arrays.toString(
charbuffer.array())
+ "\n");
// Read char at particular Index
// using charAt() method
IntStream stream = charbuffer.chars();
// Display the stream of int zero-extending
// the char values from this sequence
stream.forEach(System.out::println);
}
}
输出:
Original CharBuffer: [a, b, c] 97 98 99
范例2:
// Java program to demonstrate
// chars() method
import java.nio.*;
import java.util.*;
import java.util.stream.IntStream;
public class GFG {
public static void main(String[] args)
{
// creating object of CharBuffer
// and allocating size capacity
CharBuffer charbuffer
= CharBuffer.allocate(5);
// append the value in CharBuffer
// using append() method
charbuffer.append((char)140)
.append((char)117)
.append((char)118)
.append((char)0)
.append((char)90)
.rewind();
// print the CharBuffer
System.out.println("Original CharBuffer: "
+ Arrays.toString(
charbuffer.array())
+ "\n");
// Read char at particular Index
// using charAt() method
IntStream stream = charbuffer.chars();
// Display the stream of int zero-extending
// the char values from this sequence
stream.forEach(System.out::println);
}
}
输出:
Original CharBuffer: [?, u, v, , Z] 140 117 118 0 90
