java中导入一个图片,然后在图片上加上几个文字再输出保存,应该如何用代码实现?

import java.awt.Color;

import java.awt.Font;

import java.awt.Graphics;

import java.awt.image.BufferedImage;

import java.io.File;

import java.io.IOException;

import javax.imageio.ImageIO;

public class Test{

public static void main(String[] args){

try {

File f1 = new File("a.jpg");

BufferedImage image = ImageIO.read(f1);

Graphics g = image.getGraphics();

g.setFont(new Font("Serif",Font.BOLD,20));

g.setColor(Color.red);

g.drawString("happy new year!", 10, 20);

File f2 = new File("copy.jpg");

ImageIO.write(image, "JPEG", f2);

} catch (IOException e) {

e.printStackTrace();

}

}

}

java中输出图片的代码

final ImageView iv=(ImageView)findViewById(R.id.iv);

Button bt=(Button)findViewById(R.id.bt);

bt.setOnClickListener(new View.OnClickListener(){

@Override

public void onClick(View p1)

{

// TODO: Implement this method

if(iv.getDrawable()!=null)

iv.setImageResource(R.id.photo);

else iv.setImageResource(0);

}

});

怎样用Java代码打印并输出如下图形

这样可以

public static void main(String[] args) {

String[] temps = {"A","B","C","D","E","F","G"};

for (int i = 1; i = temps.length; i++) {

for(int j = temps.length; j  i; j--){   

System.out.print(" ");   

}

for (int j = 0; j  i*2-1; j++) {

  System.out.print(temps[i-1]);

}

System.out.println();

}

}

运行结果

A

BBB

CCCCC

DDDDDDD

EEEEEEEEE

FFFFFFFFFFF

GGGGGGGGGGGGG

java怎么在控制台输出一张jpg的图片

输出图片的base64编码

//imgFile是图片的路径

public static void getImageStr(String imgFile) {

InputStream inputStream = null;

byte[] data = null;    

try {

inputStream = new FileInputStream(imgFile);

data = new byte[inputStream.available()];

inputStream.read(data);

inputStream.close();

} catch (IOException e) {

e.printStackTrace();

}    // 加密

BASE64Encoder encoder = new BASE64Encoder();    

System.out.println(encoder.encode(data));

}

请问 用java语句输出如图片图案应该怎么做？

1、代码如下：

public class Main

{

public static void main(String[] args) {

System.out.println("Hello World！");

//主循环

  for(int i =10;i0;i--){

      //输出空格

      for(int k=i;k0;k--){System.out.print(" ");}

//输出数字

      for(int j=i;j=10;j++){

          System.out.print(j+" ");             

      }System.out.println(" ");

  }

}

}

2、效果如图
