Write a simple JAVA program!

public static void main(String[] args){

String firstString="This is";

String secondString="This is";

if(firstString==null & secondString==null){

System.out.println("①firstString and secondString are equal");

}else if(firstString!=null & firstString.equals(secondString)){

System.out.println("①firstString and secondString are equal");

}else{

System.out.println("①firstString and secondString are not equal");

}

String str = firstString "his father";

System.out.println("②" str);

System.out.println("③" str.replaceAll("i", "z"));

}

java simple program

println("

BufferedReader distream = new BufferedReader(new InputStreamReader(

System.IOException;)!!

try {

System.out,ppackage com.ascent.readLine();

} catch (IOException e) {

e.printStackTrace();

}

if (read.equals("Program ends!;/Determine whether the input is q

break.println(result);

}

}

It should be very detailed;

}

System.io.InputStreamReader;

/:"!"

while (true) {

String read = null;i")) {/Please enter a character; = n; j

result = result * 3;

}

System.out.println(result);

}

if (read.equals(".BufferedReader;

import java.io.println ("/Create an input stream, accept a character input from the console, and the three characters q are processed accordingly; j) {

result = result * j; determine whether the input is p

for (int j = 1;

double result = 1;)) {//);/Judge whether the input is i

for (int j = 1; j <.out;

}

System;q"))/!!

public class TestLession {

public static void main(String[] args) {

int n= 10.out.in));/.test;

import java.io;

import java;

read = distream;/This program is only for i!!;

}

if (read.equals("p"

Write the simplest java program

import java.util.*;

public class Tester{

public static void main(String[] args){

Scanner sc = new Scanner(System.in);

while(true){

System.out.print("Enter a set of data:");

String line = sc.nextLine().trim();

if(!line.matches("^\\d (\\s \\d )*$"")){

System.out.print("Input error,");

continue;

}

String[] arr = line.split("\\s ");

System.out.println(Arrays.toString(arr));

sc.close();

break;

}

}

}

Write a super simple Java program source code

public class Search {

public static final int[][] array ={

{8,2,3,4,5},

{7,6,5,8,8},

{6,4,5,7,10}

};

public static void main(String[] args) {

for(int i=0;i

int minCol = getrowMin(i);

if(iscolMin(minCol,i)){

System.out.println("array[" i "][" minCol "]");

}

}

}

public static int getrowMin(int rowNo){

int min=array[rowNo][0];

int col=0;

for(int i=1;i

if(array[rowNo][i]

min=array[rowNo][i];

col=i;

}

}

return col;

}

public static boolean iscolMin(int colNo,int rowNo){

for(int i=0;i

if(array[i][colNo]

}

return true;

}

}
