Novice practitioners-to review their knowledge, but also want to share experience with you:

Words don't say much, on the code

Public class bubble Sort {

/**
* @param admin
* @2017.12.4
*/
public static void Main (string[] args) {
Int[][] Array=new int[10][3]; Create a new two-dimensional array

Assigning an array (in the case of a date)
array[0][0]=2015;array[0][1]=10;array[0][2]=23;
array[1][0]=2016;array[1][1]=8;array[1][2]=14;
array[2][0]=2017;array[2][1]=3;array[2][2]=7;
array[3][0]=2018;array[3][1]=12;array[3][2]=19;
array[4][0]=2017;array[4][1]=9;array[4][2]=25;
Array[5][0]=2017;array[5][1]=6;array[5][2]=1;
array[6][0]=2017;array[6][1]=4;array[6][2]=3;
array[7][0]=2017;array[7][1]=4;array[7][2]=7;
array[8][0]=2019;array[8][1]=10;array[8][2]=6;
array[9][0]=2017;array[9][1]=12;array[9][2]=15;

int I, J, Exchange; Declare the variables you need to use, where Exchange is the equivalent of a container for swapping

Rearrange the data using the bubbling sort principle (the newest top of the date)
for (i = array.length-1; I >=1; i--) {
for (j = i; J <= Array.length-1; j + +) {
if (Array[j-1][0] < array[j][0]) {
Exchange = Array[j][0]; Array[j][0] = array[j-1][0];   ARRAY[J-1][0] = Exchange; Replacement order
Exchange = Array[j][1]; ARRAY[J][1] = array[j-1][1];   ARRAY[J-1][1] = Exchange; Replacement order
Exchange = array[j][2]; ARRAY[J][2] = array[j-1][2];   ARRAY[J-1][2] = Exchange; Replacement order

}else{
if (array[j-1][0] = = Array[j][0] && array[j-1][1] < array[j][1]) {
Exchange = Array[j][0]; Array[j][0] = array[j-1][0];   ARRAY[J-1][0] = Exchange; Replacement order
Exchange = Array[j][1]; ARRAY[J][1] = array[j-1][1];   ARRAY[J-1][1] = Exchange; Replacement order
Exchange = array[j][2]; ARRAY[J][2] = array[j-1][2];   ARRAY[J-1][2] = Exchange; Replacement order
}else{
if (array[j-1][0] = = Array[j][0] && array[j-1][1] = array[j][1] && array[j-1][2] < array[j][2]) {
Exchange = Array[j][0]; Array[j][0] = array[j-1][0];   ARRAY[J-1][0] = Exchange; Replacement order
Exchange = Array[j][1]; ARRAY[J][1] = array[j-1][1];   ARRAY[J-1][1] = Exchange; Replacement order
Exchange = array[j][2]; ARRAY[J][2] = array[j-1][2];   ARRAY[J-1][2] = Exchange; Replacement order
}
}
}
}
}

Print it out to see the effect
for (i=0;i<array.length;i++) {
SYSTEM.OUT.PRINTLN (array[i][0]+ "year" +array[i][1]+ "month" +array[i][2]+ "Day");
}
}
}
