java編程實現圖案

1. 用java編寫菱形

		回for(intm=-8;m<=8;m=m+2){
		答	for(intj=1;j<=(Math.abs(m))/2;j++){
				System.out.print("");
			}
			for(intj=1;j<=9-Math.abs(m);j++){
				System.out.print("*");
			}
			for(intj=1;j<=(Math.abs(m)-1)/2;j++){
				System.out.print("");
			}
			System.out.println();
		}

2. 如何用java編程出這個X圖案求高手詳細打出來吧！還有一個由＊組成的菱形圖案。

public class test {

public static void main(String[] args) {
int n = 7;
for (int i = 0; i < n; i++) {
for (int j = 0; j < n; j++) {
if(j == i || j == n-1-i){
System.out.print("*");
}else{
System.out.print(" ");
}
}
System.out.println();
}

}
}
n為耐首寬度缺畝擾
菱形圖案
public class test {

public static void main(String[] args) {
int n = 7;
int k = 0;
boolean falg = false;
for (int i = 0; i < n; i++) {
for (int j = 0; j < n; j++) {
if (j == n / 2 + k || j == n / 2 - k) {
System.out.print("*");
} else {
System.out.print(" "伏旦);
}
}
if (k == -3) {
falg = true;
}
if (falg) {
k++;
} else {
k--;
}
System.out.println();
}

}
}

3. 用JAVA編寫程序:輸入整數n,輸出由n行n列星號字元組成的三角形圖案

import java.io.*;
/**
* 輸入整數n,輸出由n行n列星號字元組成的三角形圖案
*
* @author user
*
*/
public class Xing2 {

public static void main(String[] args) {

System.out.print("請輸入一個正整數:");

InputStreamReader isr = new InputStreamReader(System.in);

BufferedReader br = new BufferedReader(isr);

try {

String s = br.readLine();

while (s != null) {

if (s.equalsIgnoreCase("exit"))
break;

int num = Integer.parseInt(s);

for(int i=1; i<=num; i++) {
for(int j=0; j<num-i; j++) {
System.out.print(" ");
}
for(int t=0; t<2*i-1; t++) {
System.out.print("*"中仔);
}
System.out.println();
}

System.out.println("輸入exit退出，現在就是見證奇跡的時刻！伏賀");

System.out.print("同樣請輸入一個正整數:");

s = br.readLine();

}

br.close();

} catch (IOException e) {

e.printStackTrace();

}

}

}
這缺培派是完美答案

4. 如何使用java的for的嵌套循環編寫程序，顯示出如下圖案：* ** *** **** ***** ******

使用java的for的嵌套循環編寫程序，顯示直線遞增星號圖案和直角三角形星號行岩圖案如下：

publicclassTestD{
	publicstaticvoidmain(String[]args){
		
		System.out.println("直線遞增型：");
		//直線遞增型
		for(intx=0;x<=5;x++){
			//每一組列印多少x個星號
			for(inty=0;y<=x;y++){
				System.out.print("*");
			}
			//不同組以空格隔開
			System.out.print("");
		}
		System.out.println();

		System.out.println("直角三角形：");
		//直角三角形
		for(intx=0;x<=5;x++){
			//每一組列印多少x個星號
			for(inty=0;y<=x;y++){
				System.out.print("*");
			}
			//不同組不同行需換行
			System.out.println("");
		}
		
	}
}

結果：
直線遞增型：
*********************
直角檔鋒御三角基弊形：
*
**
***
****
*****
******

5. 怎麼樣用JAVA編程語言在屏幕上顯示一個由星型符號「*」組成的金字塔圖案

自己寫的，應該能滿足你要求了。
public class Triangle {

public static void main(String[] args){
int maxLength = 10; //金字塔的邊長,可按你需求修改的
for(int m=1;m<2*maxLength;m++){
if(m<maxLength){
printBlanks(maxLength-m);
printStars(2*m-1);
} else {
printBlanks(m-maxLength);
printStars(2*(2*maxLength-m)-1);
}
System.out.println();
}
}

public static void printBlanks(int n){
for(int i=0;i<n;i++){
System.out.print(" ");
}
}

public static void printStars(int n){
for(int i=0;i<n;i++){
System.out.print("*");
}
}
}

6. java編程採用圖形界面實現兩個內容的交換,圖形界面如下圖

以下是一個簡單的Java GUI程序，可以實現兩個內容（字元串、圖片等）之間的交換：

Copy code
import java.awt.*;
import java.awt.event.*;
import javax.swing.*;

public class SwapContent extends JFrame implements ActionListener {
private JLabel label1, label2;
private JButton swapBtn;

public SwapContent() {
// 設置窗口大小和標題
setSize(400, 300);
setTitle("Swap Content Demo");

// 創建標簽和按鈕模喚
label1 = new JLabel("Content A");
label2 = new JLabel("Content B");
swapBtn = new JButton("Swap");

// 設置標簽和按鈕的位置和大小
label1.setBounds(50, 50, 100, 30);
label2.setBounds(200, 50, 100, 30);
swapBtn.setBounds(150, 150, 100, 30);

// 將標簽和按鈕添加到窗口中
add(label1);
add(label2);
add(swapBtn);

// 注冊按鈕的事件監聽器
swapBtn.addActionListener(this);

// 設置窗口的默認關閉方式
setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
}

@Override
public void actionPerformed(ActionEvent e) {
// 獲取標簽的內容
String temp = label1.getText();
label1.setText(label2.getText());
label2.setText(temp);
}

public static void main(String[] args) {
// 創建窗口對象並顯示
SwapContent sc = new SwapContent();
sc.setVisible(true);
}
}
該程序創建了一個窗口，包括兩個標簽（label1和label2）和一個按鈕（swapBtn）。當用戶點擊按鈕時，程序會交換label1和label2的內容。

在程序的actionPerformed方法中，程序將label1和label2的內容交換。具體實現是，首先使用旦冊凱label1.getText()獲取label1的內容，並將其保存到一個臨時變數temp中；然後，將label1的內容設置為label2的內容，將label2的內容設置為temp的姿裂值。這樣，label1和label2的內容就被互換了。

在main方法中，程序創建了SwapContent對象，並將其顯示出來。程序運行後，用戶可以在窗口中交換label1和label2的內容。

7. java 菱形圖案 要求用while編寫

public class Lingxing {
public static void main(String[] args) {
while (true) {
System.out.println("滲殲請輸入菱形的拿搜高（是奇數哦,不是數字退出）：");
InputStreamReader ir;
BufferedReader in;
ir = new InputStreamReader(System.in);
in = new BufferedReader(ir);
try {
String s = in.readLine();
int ii = Integer.parseInt(s);
System.out.println(ii);
int rows = (ii + 1) / 2;
for (int i = 1; i <= rows; i++) {
for (int j = 1; j <= rows - i; j++) {
System.out.print(" ");
}
for (int j = 1; j <= i * 2 - 1; j++) {
System.out.print("*");
}
System.out.println();
}
for (int i = 1; i <= rows - 1; i++) {
for (int j = 1; j <= i; j++) {
System.out.print(" "叢敏沖);
}
for (int j = 2 * rows - 1; j >= i * 2 + 1; j--) {
System.out.print("*");
}
System.out.println();
}

} catch (Exception e) {
}

}

}

}

8. 怎樣用JAVA繪制一個菱形圖案

java 輸出菱形代碼：

1
2
3
4
5
6
7
8
9
10
11
12
13
14
15
16
17
18
19
20
21
22

package demo;

public class Demo01 {
public static void main(String[] args) {
int i, j, k;
for (i = 1; i <= 5; i++) {
for (j = 1; j <= 5 - i; j++)
System.out.print(" ");
for (k = 1; k <= 2 * i - 1; k++)
System.out.print("*");
System.out.println("");
}

for (i = 1; i <= 4; i++) {
for (j = 1; j <= i; j++)
System.out.print(" ");
for (k = 1; k <= 9 - 2 * i; k++)
System.out.print("*");
System.out.println("");
}
}
}

繪制演算法：
1、分為兩部分，上半部分和下半部分
2、輸出空版格部分換個輸出*部分
3、最後權一個標簽需要換行
