Detailed explanation of examples of transposing two-dimensional arrays in Java

This article mainly introduces the method of realizing two-dimensional array transposition in java. It analyzes the principle, implementation steps and related operation skills of java two-dimensional array transposition in detail in the form of examples. Friends in need can refer to it

The example in this article describes the method of transposing a two-dimensional array in Java. Share it with everyone for your reference, the details are as follows:

Here, create three classes: Test2, Exchange, and Out in the file

Write the exchange() method in the Exchange class, and create two Arrays arrayA, arrayB, arraryB[j][i]=arraryA[i][j] implements the transposition of the array.

Write the out() method in the Out class, and use a for loop to traverse the method to achieve output.

The specific code is as follows:

package Tsets;
import java.util.*;
public class Test2
{
    public static void main(String args[])
    {
        Out T1=new Out();
        Out T2=new Out();
        Exchange E=new Exchange();
        System.out.println("脚本之家测试结果：");
        System.out.println("转置前的二维数组如下：");
        T1.out(E.arraryA);
        E.exchange();
        System.out.println("转置后的二维数组如下：");
        T2.out(E.arraryB);
    }
}
//数组转置
class Exchange
{
    int arraryA[][]={{11,12,13,14,15},{21,22,23,24,25},{31,32,33,34,35},{41,42,43,44,45},{51,52,53,54,55}};
    int arraryB[][] = new int[arraryA[0].length][arraryA.length];
    public void exchange ()
    {
        for(int i=0;i<arraryA.length;i++)
        {
            for(int j=0;j<arraryA[i].length;j++)
            {
                arraryB[j][i]=arraryA[i][j];
            }
        }
    }
}
//数字循环遍历输出
class Out
{
    public void out(int c[][])
    {
        for (int i=0;i<c.length ;i++ )
        {
            for (int j=0;j<c[i].length ;j++ )
            {
                System.out.print(c[i][j]+" ");
            }
            System.out.println();
        }
    }
}
