java中導(dǎo)入一個圖片,然后在圖片上加上幾個文字再輸出保存,應(yīng)該如何用代碼實現(xiàn)?

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中輸出圖片的代碼

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);

}

});

怎樣用Java代碼打印并輸出如下圖形

這樣可以

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();

}

}

java怎么在控制臺輸出一張jpg的圖片

輸出圖片的base64編碼

//imgFile是圖片的路徑

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));

}

請問 用java語句輸出如圖片圖案應(yīng)該怎么做？

1、代碼如下：

public class Main

{

public static void main(String[] args) {

System.out.println("Hello World！");

//主循環(huán)

? for(int i =10;i0;i--){

? ? ? //輸出空格

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

//輸出數(shù)字

? ? ? for(int j=i;j=10;j++){

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

? ? ? }System.out.println(" ");

? }

}

}

2、效果如圖
