Java中PrintStream類的append(CharSequence)方法用於在流上寫入指定的CharSequence。此CharSequence值用作參數。
用法:
public PrintStream append(CharSequence charSequence)
參數:此方法接受強製參數charSequence,該參數是要寫入流中的CharSequence。
返回值:此方法返回此PrintStream實例。
下麵的方法說明了append(CharSequence)方法的用法方式:
示例1:
// Java program to demonstrate
// PrintStream append(CharSequence) method
import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a PrintStream instance
PrintStream stream
= new PrintStream(System.out);
// Write the CharSequence 'GeeksForGeeks'
// to this stream using append() method
// This will put the charSequence in the stream
// till it is printed on the console
stream.append("GeeksForGeeks");
stream.flush();
}
catch (Exception e) {
System.out.println(e);
}
}
}
輸出:
GeeksForGeeks
示例2:
// Java program to demonstrate
// PrintStream append(CharSequence) method
import java.io.*;
class GFG {
public static void main(String[] args)
{
try {
// Create a PrintStream instance
PrintStream stream
= new PrintStream(System.out);
// Write the CharSequence 'GFG'
// to this stream using append() method
// This will put the charSequence in the stream
// till it is printed on the console
stream.append("GFG");
stream.flush();
}
catch (Exception e) {
System.out.println(e);
}
}
}
輸出:
GFG
